The title organic–inorganic hybrid compound, [Co(C10H8N2O2)2(H2O)2]2[Mo8O26]·2H2O, consists of [Co(bpdo)2(H2O)2]2+ (bpdo is 2,2‐bipyridine N,N′‐dioxide) and ξ‐[Mo8O26]4− groups in a 2:1 ratio, plus two water solvent molecules. The independent Co atom in the cation is coordinated by four O atoms from two bpdo ligands and two water molecules, in a distorted octahedral geometry. The counter‐anions, built up around a symmetry center, are linked by solvent water molecules through O—H...O hydrogen bonds to generate two‐dimensional layers, which are in turn linked by coordinated water molecules from the cationic units through further O—H...O hydrogen bonds, forming a three‐dimensional supramolecular structure. 相似文献

The crystal structure of the title compound, {[Tm(C8H3O7S)(H2O)5]·1.5C10H8N2·0.5H2O}n, is built up from two [Tm(SIP)(H2O)5] molecules (SIP3− is 5‐sulfonatobenzene‐1,3‐dicarboxylate), three 4,4′‐bipyridyl (bpy) molecules and one solvent water molecule. One of the bpy molecules and the solvent water molecule are located on an inversion centre and a twofold rotation axis, respectively. The TmIII ion coordination is composed of four carboxylate O atoms from two trianionic SIP3− ligands and five coordinated water molecules. The Tm3+ ions are linked by the SIP3− ligands to form a one‐dimensional zigzag chain propagating along the c axis. The chains are linked by interchain O—H...O hydrogen bonds to generate a two‐dimensional layered structure. The bpy molecules are not involved in coordination but are linked by O—H...N hydrogen bonds to form two‐dimensional layers. The two‐dimensional layers are further bridged by the bpy molecules as pillars and the solvent water molecules through hydrogen bonds, giving a three‐dimensional supramolecular structure. π–π stacking interactions between the parallel aromatic rings, arranged in an offset fashion with a face‐to‐face distance of 3.566 (1) Å, are observed in the crystal packing. 相似文献

The title compound, {[CoLi2(C11H14N2O8)(H2O)3]·2H2O}n, constitutes the first example of a salt of the [MII(1,3‐pdta)]2− complex (1,3‐pdta is propane‐1,3‐diyldinitrilotetraacetate) with a monopositive cation as counter‐ion. Insertion of the Li+ cation could only be achieved through application of the ion‐exchange column technique which, however, appeared unsuccessful with other alkali metals and the ammonium cation. The structure contains two tetrahedrally coordinated Li+ cations, an octahedral [Co(1,3‐pdta)]2− anion and five water molecules, two of which are uncoordinated, and is built of two‐dimensional layers extending parallel to the (010) lattice plane, the constituents of which are connected by the coordinate bonds. O—Hwater...O hydrogen bonds operate both within and between these layers. The crystal investigated belongs to the enantiomeric space group P21 with only one (Λ) of two possible optical isomers of the [Co(1,3‐pdta)]2− complex. A possible cause of enantiomer separation during crystallization might be the rigidification and polarization of the [M(1,3‐pdta)]2− core, resulting from direct coordination of Li+ cations to three out of four carboxylate groups constituting the 1,3‐pdta ligand. The structure of (I) differs considerably from those of the other [MII(1,3‐pdta)]2− complexes, in which the charge compensation is realized by means of divalent hexaaqua complex cations. This finding demonstrates a significant structure‐determining role of the counter‐ions. 相似文献

The title compound, [Co(C10H8N2)3]2[V4O12]·11H2O, is composed of two symmetry‐related cations containing octahedrally coordinated CoII ions, a centrosymmetric [V4O12]4− anion with an eight‐membered ring structure made up of four VO4 tetrahedra, and 11 solvent water molecules. The CoII cations and vanadate anions are isolated and build cation and anion layers, respectively. In addition, the title compound exhibits a three‐dimensional network through intra‐ and intermolecular hydrogen‐bond interactions between water molecules and O atoms of the anions, and the crystal structure is stabilized mainly by hydrogen bonds. 相似文献

In the title compound, [Mn(C5H2N2O4)(C12H9N3)2]·H2O, the MnII centre is surrounded by three bidentate chelating ligands, namely, one 6‐oxido‐2‐oxo‐1,2‐dihydropyrimidine‐5‐carboxylate (or uracil‐5‐carboxylate, Huca2−) ligand [Mn—O = 2.136 (2) and 2.156 (3) Å] and two 2‐(2‐pyridyl)‐1H‐benzimidazole (Hpybim) ligands [Mn—N = 2.213 (3)–2.331 (3) Å], and it displays a severely distorted octahedral geometry, with cis angles ranging from 73.05 (10) to 105.77 (10)°. Intermolecular N—H...O hydrogen bonds both between the Hpybim and the Huca2− ligands and between the Huca2− ligands link the molecules into infinite chains. The lattice water molecule acts as a hydrogen‐bond donor to form double O...H—O—H...O hydrogen bonds with the Huca2− O atoms, crosslinking the chains to afford an infinite two‐dimensional sheet; a third hydrogen bond (N—H...O) formed by the water molecule as a hydrogen‐bond acceptor and a Hpybim N atom further links these sheets to yield a three‐dimensional supramolecular framework. Possible partial π–π stacking interactions involving the Hpybim rings are also observed in the crystal structure. 相似文献

The title compound, [CuNa(C4H3O7S)(C10H8N2)(H2O)3]n, consists of one CuII cation, one NaI cation, one 2‐sulfonatobutanedioate trianion (SSC3−), one 2,2′‐bipyridyl (bpy) ligand and three coordinated water molecules as the building unit. The coordination of the CuII cation is composed of two pyridyl N atoms, one water O atom and two carboxylate O atoms in a distorted square‐pyramidal coordination geometry with an axial elongation. The NaI cation is six‐coordinated by three water molecules and three carboxylate O atoms from three SSC3− ligands in a distorted octahedral geometry. Two SSC3− ligands link two CuII cations to form a Cu2(SSC)2(bpy)2 macrocyclic unit lying across an inversion centre, which is further linked by NaI cations via Na—O bonds to give a one‐dimensional chain. Interchain hydrogen bonds link these chains to form a two‐dimensional layer, which is further extended into a three‐dimensional supramolecular framework through π–π stacking interactions. The thermal stability of the title compound has also been investigated. 相似文献

The title compound, {(C7H15N2Cl)2[Cd3Cl10]·4H2O}n, consists of 1‐chloromethyl‐1,4‐diazoniabicyclo[2.2.2]octane dications, one‐dimensional inorganic chains of {[Cd3Cl10]4−} anions and uncoordinated water molecules. Each of the two independent CdII ions, one with site symmetry 2/m and the other with site symmetry m, is octahedrally coordinated by chloride ions (two with site symmetry m and one with site symmetry 2), giving rise to novel polymeric zigzag chains of corner‐sharing Cd‐centred octahedra parallel to the c axis. The organic cations, bisected by mirror planes that contain the two N atoms, three methylene C atoms and the Cl atom, are ordered. Hydrogen bonds (O—H...Cl and O—H...O) between the water molecules (both with O atoms in a mirror plane) and the chloride anions of neighbouring chloridocadmate chains form a three‐dimensional supramolecular network. 相似文献

The title compound, {[Co(C8H7NO2)2(H2O)2](NO3)2}n, is the first d‐metal ion complex involving bidentate bridging of a β‐dialdehyde group. The Co2+ ion is situated on an inversion centre and adopts an octahedral coordination with four equatorial aldehyde O atoms [Co—O = 2.0910 (14) and 2.1083 (14) Å] and two axial aqua ligands [Co—O = 2.0631 (13) Å]. The title compound has a two‐dimensional square‐grid framework structure supported by propane‐1,3‐dionate O:O′‐bridges between the metal ions. The organic ligand itself possesses a zwitterionic structure, involving conjugated anionic propane‐1,3‐dionate and cationic pyridinium fragments. Hydrogen bonding between coordinated water molecules, the pyridinium NH group and the nitrate anions [O...O = 2.749 (2) and 2.766 (3) Å, and N...O = 2.864 (3) Å] is essential for the crystal packing. 相似文献

The asymmetric unit in the structure of the title compound, [K2(C9H4O9S)(H2O)2]n, consists of two eight‐coordinated KI cations, one 2,4‐dicarboxy‐5‐sulfonatobenzoate dianion (H2SBTC2−), one bridging water molecule and one terminal coordinated water molecule. One KI cation is coordinated by three carboxylate O atoms and three sulfonate O atoms from four H2SBTC2− ligands and by two bridging water molecules. The second KI cation is coordinated by four sulfonate O atoms and three carboxylate O atoms from five H2SBTC2− ligands and by one terminal coordinated water molecule. The KI cations are linked by sulfonate groups to give a one‐dimensional inorganic chain with cage‐like K4(SO3)2 repeat units. These one‐dimensional chains are bridged by one of the carboxylic acid groups of the H2SBTC2− ligand to form a two‐dimensional layer, and these layers are further linked by the remaining carboxylate groups and the benzene rings of the H2SBTC2− ligands to generate a three‐dimensional framework. The compound displays a photoluminescent emission at 460 nm upon excitation at 358 nm. In addition, the thermal stability of the title compound has been studied. 相似文献

The title compound, {[Ag(C13H14N2)](C10H6O6S2)0.5·2H2O}n, (I), features a three‐dimensional supramolecular sandwich architecture that consists of two‐dimensional cationic layers composed of polymeric chains of silver(I) ions and 1,3‐bis(4‐pyridyl)propane (bpp) ligands, linked by Ag...Ag and π–π interactions, alternating with anionic layers in which uncoordinated naphthalene‐1,5‐disulfonate (nds2−) anions and solvent water molecules form a hydrogen‐bonded network. The asymmetric unit consists of one AgI cation linearly coordinated by N atoms from two bpp ligands, one bpp ligand, one half of an nds2− anion lying on a centre of inversion and two solvent water molecules. The two‐dimensional {[Ag(bpp)]+}n cationic and {[(nds)·2H2O]2−}n anionic layers are assembled into a three‐dimensional supramolecular framework through long secondary coordination Ag...O interactions between the sulfonate O atoms and AgI centres and through nonclassical C—H...O hydrogen bonds. 相似文献

Molecules of 1,3‐dimethyl‐7‐(4‐methylphenyl)pyrido[2,3‐d]pyrimidine‐2,4(1H,3H)‐dione, C16H15N3O2, (I), are linked by paired C—H...O hydrogen bonds to form centrosymmetric R22(10) dimers, which are linked into chains by a single π–π stacking interaction. A single C—H...O hydrogen bond links the molecules of 7‐(biphenyl‐4‐yl)‐1,3‐dimethylpyrido[2,3‐d]pyrimidine‐2,4(1H,3H)‐dione, C21H17N3O2, (II), into C(10) chains, which are weakly linked into sheets by a π–π stacking interaction. In 7‐(4‐fluorophenyl)‐3‐methylpyrido[2,3‐d]pyrimidine‐2,4(1H,3H)‐dione, C14H10FN3O2, (III), an N—H...O hydrogen bond links the molecules into C(6) chains, which are linked into sheets by a π–π stacking interaction. The molecules of 7‐(4‐methoxyphenyl)‐3‐methylpyrido[2,3‐d]pyrimidine‐2,4(1H,3H)‐dione, C15H13N3O3, (IV), are also linked into C(6) chains by an N—H...O hydrogen bond, but here the chains are linked into sheets by a combination of two independent C—H...π(arene) hydrogen bonds. 相似文献

Poly[bis(3,3′,5,5′‐tetramethyl‐4,4′‐bi‐1H‐pyrazole‐2,2′‐diium) γ‐octamolybdate(VI) dihydrate], {(C10H16N4)2[Mo8O26]·2H2O}n, (I), and bis(3,3′,5,5′‐tetramethyl‐4,4′‐bi‐1H‐pyrazole‐2,2′‐diium) α‐dodecamolybdo(VI)silicate tetrahydrate, (C10H16N4)2[SiMo12O40]·4H2O, (II), display intense hydrogen bonding between the cationic pyrazolium species and the metal oxide anions. In (I), the asymmetric unit contains half a centrosymmetric γ‐type [Mo8O26]4− anion, which produces a one‐dimensional polymeric chain by corner‐sharing, one cation and one water molecule. Three‐centre bonding with 3,3′,5,5′‐tetramethyl‐4,4′‐bi‐1H‐pyrazole‐2,2′‐diium, denoted [H2Me4bpz]2+ [N...O = 2.770 (4)–3.146 (4) Å], generates two‐dimensional layers that are further linked by hydrogen bonds involving water molecules [O...O = 2.902 (4) and 3.010 (4) Å]. In (II), each of the four independent [H2Me4bpz]2+ cations lies across a twofold axis. They link layers of [SiMo12O40]4− anions into a three‐dimensional framework, and the preferred sites for pyrazolium/anion hydrogen bonding are the terminal oxide atoms [N...O = 2.866 (6)–2.999 (6) Å], while anion/aqua interactions occur preferentially viaμ2‐O sites [O...O = 2.910 (6)–3.151 (6) Å]. 相似文献

The crystal structure of the title compound, (C4H15N3)2[Mo5O15(HPO4)2]·4H2O, is made up of [Mo5O15(HPO4)2]4− clusters, iminodiethylenediammonium cations and solvent water molecules. The [Mo5O15(HPO4)2]4− cluster, with approximate C2 symmetry, can be considered as a ring formed by five distorted edge‐ and corner‐sharing MoO6 octahedra, capped on both poles by a hydrophosphate tetrahedron. There exist N—H⋯O, O—H⋯N and C—H⋯O hydrogen bonds between the organic ammonium groups and the clusters, with interatomic N⋯O distances ranging from 2.675 (3) to 2.999 (3) Å, and C⋯O distances ranging from 3.139 (5) to 3.460 (5) Å. 相似文献

The title compound, [Cd3(C8H10O4)3(C12H9N3)2(H2O)2]n or [Cd3(chdc)3(4‐PyBIm)2(H2O)2]n, was synthesized hydrothermally from the reaction of Cd(CH3COO)2·2H2O with 2‐(pyridin‐4‐yl)‐1H‐benzimidazole (4‐PyBIm) and cyclohexane‐1,4‐dicarboxylic acid (1,4‐chdcH2). The asymmetric unit consists of one and a half CdII cations, one 4‐PyBIm ligand, one and a half 1,4‐chdc2− ligands and one coordinated water molecule. The central CdII cation, located on an inversion centre, is coordinated by six carboxylate O atoms from six 1,4‐chdc2− ligands to complete an elongated octahedral coordination geometry. The two terminal rotationally symmetric CdII cations each exhibits a distorted pentagonal–bipyramidal geometry, coordinated by one N atom from 4‐PyBIm, five O atoms from three 1,4‐chdc2− ligands and one O atom from an aqua ligand. The 1,4‐chdc2− ligands possess two conformations, i.e.e,e‐trans‐chdc2− and e,a‐cis‐chdc2−. The cis‐1,4‐chdc2− ligands bridge the CdII cations to form a trinuclear {Cd3}‐based chain along the b axis, while the trans‐1,4‐chdc2− ligands further link adjacent one‐dimensional chains to construct an interesting two‐dimensional network. 相似文献

The title complex, [CaCu(C5H6O4)2(H2O)2]n, is the first heterobimetallic complex based on a substituted malonate dianion. The CuII cation and two independent 2,2‐dimethylmalonate (or 2,2‐dimethylpropanedioate) dianions build up a robust dianionic [Cu(C5H6O4)2]2− complex, which acts as a building block to coordinate to four Ca2+ cations. Each CuII centre is in a four‐coordinate square plane of dimethylmalonate O atoms, while each CaII atom is in an eight‐coordinate distorted bicapped trigonal–prismatic environment of six O atoms from four different dimethylmalonate groups and two water molecules. This arrangement creates a two‐dimensional layer connectivity of the structure. The dianionic [Cu(C5H6O4)2]2− units are involved in different intermolecular hydrogen‐bonding interactions with water molecules via the formation of hydrogen‐bonded rings of graph sets R12(8) and R(6) within this layer. The crystal was nonmerohedrally twinned by rotation about [011] with a major twin volume fraction of 0.513 (3). 相似文献

The title compound, {(C6H14N2O2)[Cu2Cl6(H2O)]}n, consists of 1,4‐dihydroxy‐1,4‐diazoniabicyclo[2.2.2]octane dications and one‐dimensional inorganic anionic {[Cu2Cl6(H2O)]2−}n chains in which both five‐coordinate [CuCl3(H2O)]− and five‐coordinate [CuCl3]− units exist. These two distinct type of unit are linked together by one chloride ion and are bridged across centres of inversion to further units of their own type through two chloride ions, giving rise to novel polymeric zigzag chains parallel to the c axis. The chains are connected by O—H...Cl hydrogen bonds to produce R24(16) ring motifs, resulting in two‐dimensional layers parallel to the ac plane. These layers are linked into a three‐dimensional framework with the organic cations via O—H...Cl hydrogen bonds. Hydrogen bonding between the chains, and between the chains and the organic cations, provides stability to the crystal structure. 相似文献

The asymmetric unit of the title coordination polymer, [Gd2(C7H4O5S)2(C2O4)(H2O)6]n or [Gd(2‐SB)(ox)0.5(H2O)3]2n (2‐SB is 2‐sulfonatobenzoate and ox is oxalate), (I), consists of one GdIII ion, one 2‐SB anion, three coordinated water molecules and one half of an ox ligand. The ox ligand is located on a crystallographic inversion centre. The GdIII centre shows a distorted tricapped trigonal–prismatic coordination formed by nine O atoms from two 2‐SB anions, one ox ligand and three coordinated water molecules. The carboxylate and sulfonate groups of the 2‐SB anions adopt μ2‐η1:η2 and μ1‐η0:η0:η1 coordination modes to link two GdIII ions, generating a centrosymmetric binuclear [Gd2(2‐SB)2(H2O)6]2− subunit. The ox ligand acts as a bridge, linking the binuclear [Gd2(2‐SB)2(H2O)6]2− subunits into a one‐dimensional chain structure parallel to the b axis. Furthermore, extensive O—H...O hydrogen bonds connect the chains into a three‐dimensional supramolecular architecture. 相似文献

A novel three‐dimensional coordination polymer, {[Pb(C14H8N2O4)(H2O)]·0.5C12H10N2}n, has been synthesized by hydrothermal reaction of Pb(OAc)2·3H2O (OAc is acetate), 2,2′‐(diazene‐1,2‐diyl)dibenzoic acid (H2L) and 1,2‐bis(pyridin‐4‐yl)ethylene (bpe). The asymmetric unit contains a crystallographically independent PbII cation, one L2− ligand, an aqua ligand and half a bpe molecule. Each PbII centre is seven‐coordinated by six O atoms of bridging–chelating carboxylate groups from L2− ligands and by one O atom from a coordinated water molecule. The PbII cations are bridged by L2− ligands, forming [PbO2]n chains along the a axis. These chains are further connected by L2− ligands along the b and c axes to give a three‐dimensional framework with a 41263 topology. The channel voids are occupied by bpe molecules. 相似文献
