In the title two‐dimensional coordination polymer, [Mn(1,4‐BDOA)(4,4‐bipy)(H2O)2]n [1,4‐BDOA2− is the p‐phenylenedioxydiacetate dianion (C10H8O6) and 4,4‐bipy is 4,4‐bipyridine (C10H8N2)], each MnII atom displays octahedral coordination by two O atoms of the 1,4‐BDOA2− groups, two N atoms of the 4,4‐bipy ligands and two solvent water molecules. The MnII atom, 4,4‐bipy ligand and 1,4‐BDOA2− group occupy different inversion centres. Adjacent MnII atoms are bridged by 1,4‐BDOA2− groups and 4,4‐bipy ligands, forming a two‐dimensional network with Mn⋯Mn separations of 11.592 (2) and 11.699 (2) Å. Hydrogen bonds from a water O—H group link the layers in the third dimension. 相似文献

In the title coordination polymer, {[Ba(C8H5Cl2O3)2(H2O)]·H2O}n, each BaII atom is nine‐coordinated by six carboxylate O atoms and one ether O atom from five symmetry‐related 2,4‐dichlorophenoxyacetate ligands, and by two O atoms from water molecules, thus defining a distorted tricapped trigonal prism. The BaII ions are bridged by bidentate water molecules and by tridentate and tetradentate 2,4‐dichlorophenoxyacetate groups, leading to a two‐dimensional layer structure. The crystal structure is further stabilized by hydrogen‐bonding interactions within each layer. 相似文献

It is interesting to note that the HIDC2− group serves as a bridging ligand to link the PbII atoms into a three‐dimensional microporous open‐framework. 相似文献

In the title three‐dimensional coordination polymer, [Sr(4‐CPOA)(H2O)]n (where 4‐CPOA2− is the 4‐carboxylatophenoxyacetate dianion, C9H6O5), each SrII atom displays a bicapped triangular prismatic configuration, defined by five carboxyl and one ether O atom from five different 4‐CPOA2− ligands, as well as two water molecules. The SrII atoms are covalently linked by 4‐CPOA2− ligands and water molecules, giving rise to a three‐dimensional open framework. In previously studied polymers of this type, the 4‐CPOA2− ligand shows a variety of binding modes to metal ions, from mono‐ to pentadentate. In the present SrII complex, a novel hexadentate bridging mode is observed. 相似文献

The reaction of Ni(CH3COO)2·4H2O, 5‐nitro‐1,3‐benzenedicarboxylic acid (H2nmbdc), 1,10‐phenanthroline and water under hydrothermal conditions yields the first reported two‐dimensional nickel coordination polymer with water‐ and carboxylate‐bridged dimeric units, viz. [Ni2(C8H3NO6)2(C12H8N2)2(H2O)]n. The coordination polyhedron of the NiII ion in the title structure is an octahedron defined by an N2O4 donor set. The water molecule is positioned on a mirror plane and the 5‐nitro‐1,3‐benzenedicarboxylate group is located on a twofold axis. Two types of nmbdc2− coordination mode are observed: one is a bis‐monodentate mode, μ2‐nmbdc2−, and the other is a bis‐bridging mode, μ4‐nmbdc2−. The dimeric unit in the title compound is similar to the structural moiety in urease. In the two‐dimensional framework in the title compound, strong stacking interactions between benzene rings (μ2‐nmbdc2− and μ4‐nmbdc2−) and 1,10‐phenanthroline ligands are observed. 相似文献

In the title compound, [Cu(C10H4O8)(C12H8N2)]n, the CuII cation has a four‐coordination environment completed by two N atoms from one 1,10‐phenanthroline (phen) ligand and two O atoms belonging to two dihydrogen benzene‐1,2,4,5‐tetracarboxylate anions (H2TCB2−). There is a twofold axis passing through the CuII cation and the centre of the phen ligand. The [Cu(phen)]2+ moieties are bridged by H2TCB2− anions to form an infinite one‐dimensional coordination polymer with a zigzag chain structure along the c axis. A double‐chain structure is formed by hydrogen bonds between adjacent zigzag chains. Furthermore, there are π–π stacking interactions between the phen ligands, with an average distance of 3.64 Å, resulting in a two‐dimensional network structure. 相似文献

In the title polymer, [Pb(C9H4O6)]n, the asymmetric unit contains a monomer of a PbII cation with a doubly deprotonated 3‐carboxybenzene‐1,2‐dicarboxylate dianion (1,2,3‐Hbtc2−). Each PbII centre is seven‐coordinated by seven O atoms of bridging carboxy/carboxylate groups from five 1,2,3‐Hbtc2− ligands, forming a distorted pentagonal bipyramid. The PbII cations are bridged by 1,2,3‐Hbtc2− anions, yielding two‐dimensional chiral layers. The layers are stacked above each other to generate a three‐dimensional supramolecular architecture via a combination of C—H...O interactions. The thermogravimetric and optical properties are also reported. 相似文献

In the title compound, {[Co(SO4)(C10H8N2)(H2O)3]·C2H6O2}n, each CoII center is octahedrally coordinated by two N atoms from two bridging 4,4′‐bipyridine (bipy) ligands and four O atoms, one from a monodentate sulfate ligand and three from aqua ligands. The bipy ligands occupy special positions of site symmetry and bridge adjacent cobalt(II) centers to form one‐dimensional linear coordination chains. Adjacent chains are arranged in a cross‐like fashion around the mid‐point of the bipy ligands, resulting in a three‐dimensional supramolecular array. 相似文献

In the title compound, [Mn(C5H2N2O4)(H2O)2]n, the MnII ion has a distorted octahedral geometry and the 4‐oxido‐2‐oxo‐1,2‐dihydropyrimidine‐5‐carboxylate (Hiso2−) anion acts as a μ3:η4‐bridging ligand. Two oxo O atoms from different Hiso2− ligands bridge two MnII ions, forming centrosymmetric dinuclear building blocks. Each dinuclear building block interacts with another four by the coordination of the oxide groups and carboxylate O atoms, producing a two‐dimensional framework in the ab plane. Hydrogen bonds further extend the two‐dimensional sheets into a three‐dimensional supramolecular framework. 相似文献

Two new two‐dimensional coordination polymers, poly[[[aqua(2,2′‐bipyridine‐κ2N,N′)manganese(II)]‐μ3‐p‐phenylenebis(oxyacetato)‐κ3O:O′:O′′] dihydrate], {[Mn(C10H8O6)(C10H8N2)(H2O)]·2H2O}n, (I), and poly[[di‐μ‐aqua‐bis[aquasodium(I)]]‐μ4‐p‐phenylenebis(oxyacetato)‐κO:O′,O′′:O′′′,O′′′′:O′′′′′], [Na2(C10H8O6)(H2O)4]n, (II), have been synthesized and characterized by X‐ray single‐crystal diffraction. In (I), there are two 1,4‐BDOA2− [p‐phenylenebis(oxyacetate) or, more commonly, benzene‐1,4‐dioxyacetate] ligands, each lying about inversion centres, while in (II), there is one such ligand and it also has crystallographically imposed inversion symmetry. In (I), each MnII atom displays an octahedral MnN2O4 configuration, defined by three carboxyl O atoms of different 1,4‐BDOA2− groups, two N atoms of one 2,2′‐bipyridine ligand and one water molecule. In (II), each NaI atom is octahedrally coordinated by one ether O atom, two carboxyl O atoms of different 1,4‐BDOA2− ligands and three water molecules. The metal ions in complexes (I) and (II) are bridged by 1,4‐BDOA2− groups into two‐dimensional layer structures. Furthermore, three‐dimensional supramolecular networks are constructed via hydrogen bonds in (I) and (II), and by additional π–π stacking interactions in (I). 相似文献

A novel copper(II) coordination polymer, poly[[[aquacopper(II)]‐μ3‐2,2′‐bipyridyl‐3,3′‐dicarboxylato‐κ4N,N′:O:O′] dihydrate], {[Cu(C12H6N2O4)(H2O)]·2H2O}n, was obtained by the reaction of CuCl2·2H2O and 2,2′‐bipyridyl‐3,3′‐dicarboxylic acid (H2L) in water. In the molecule, each CuII atom is five‐coordinated and lies at the centre of a square‐pyramidal basal plane, bridged by three L ligands to form a two‐dimensional (4,4)‐network. Each L moiety acts as a bridging tetradentate ligand, coordinating to three CuII atoms through its two aromatic N atoms and two O atoms of the two carboxyl groups. The two‐dimensional square‐grid sheets superimpose in an off‐set fashion through the inorganic water layer. 相似文献

In the title coordination polymer, {[Cd(C6H8O4S)(C13H14N2)]·H2O}n, the CdII atom displays a distorted octahedral coordination, formed by three carboxylate O atoms and one S atom from three different 3,3′‐thiodipropionate ligands, and two N atoms from two different 4,4′‐(propane‐1,3‐diyl)dipyridine ligands. The CdII centres are bridged through carboxylate O atoms of 3,3′‐thiodipropionate ligands and through N atoms of 4,4′‐(propane‐1,3‐diyl)dipyridine ligands to form two different one‐dimensional chains, which intersect to form a two‐dimensional layer. These two‐dimensional layers are linked by S atoms of 3,3′‐thiodipropionate ligands from adjacent layers to form a three‐dimensional network. 相似文献

The title CdII compound, {[Cd2(C13H7NO4)2(H2O)4]·5H2O}n, was synthesized by the hydrothermal reaction of Cd(NO3)2·4H2O and 5‐(pyridin‐4‐yl)isophthalic acid (H2L). The asymmetric unit contains two crystallographically independent CdII cations, two deprotonated L2− ligands, four coordinated water molecules and five isolated water molecules. One of the CdII cations adopts a six‐coordinate octahedral coordination geometry involving three O atoms from one bidentate chelating and one monodentate carboxylate group of two different L2− ligands, one N atom of another L2− ligand and two coordinated water molecules. The second CdII cation adopts a seven‐coordinate pentagonal–bipyramidal coordination geometry involving four O atoms from two bidentate chelating carboxylate groups of two different L2− ligands, one N atom of another L2− ligand and two coordinated water molecules. Each L2− ligand bridges three CdII cations and, likewise, each CdII cation connects to three L2− ligands, giving rise to a two‐dimensional graphite‐like 63 layer structure. These two‐dimensional layers are further linked by O—H...O hydrogen‐bonding interactions to form a three‐dimensional supramolecular architecture. The photoluminescence properties of the title compound were also investigated. 相似文献

In the title compound [systematic name: triaqua(1,4,7,10,13,16‐hexaoxacyclooctadecane‐κ6O)(2‐nitrophenolato‐κO)barium(II)–aqua(1,4,7,10,13,16‐hexaoxacyclooctadecane‐κ6O)‐ bis(2‐nitrophenolato‐κ2O,O′)barium(II)–2‐nitrophenolate (1/1/1)], [Ba(C12H24O6)(C6H4NO3)(H2O)3][Ba(C12H24O6)(C6H4NO3)2(H2O)](C6H4NO3), the two BaII atoms encapsulated by the 18‐crown‐6 rings have different coordinations. Although both BaII atoms are coordinated to the six O atoms of the crowns, in the neutral moiety, the BaII atom is coordinated to one terminal O atom from a water molecule, two phenolate O atoms and two nitro‐group O atoms, while in the cationic moiety, the BaII atom is coordinated to three terminal O atoms from water molecules and one phenolate O atom. Both the crowns are eclipsed and translated along the b direction. In the asymmetric unit, the three components are interconnected by four O—H?O interactions. The packing is stabilized by two intermolecular C—H?O interactions and by one O—H?O interaction. 相似文献

The title novel heterometallic 3d–4f coordination polymer, {[CuEr2(C5HN2O4)2(C2O4)(H2O)6]·3H2O}n, has a three‐dimensional metal–organic framework composed of two types of metal atoms (one CuII and two ErIII) and two types of bridging anionic ligands [3,5‐dicarboxylatopyrazolate(3−) (ptc3−) and oxalate]. The CuII atom is four‐coordinated in a square geometry. The ErIII atoms are both eight‐coordinated, but the geometries at the two atoms appear different, viz. triangular dodecahedral and bicapped trigonal prismatic. One of the oxalate anions is located on a twofold axis and the other lies about an inversion centre. Both oxalate anions act as bis‐bidentate ligands bridging the latter type of Er atoms in parallel zigzag chains. The pdc3− anions act as quinquedentate ligands not only chelating the CuII and the triangular dodecahedral ErIII centres in a bis‐bidentate bridging mode, but also connecting to ErIII centres of both types in a monodentate bridging mode. Thus, a three‐dimensional metal–organic framework is generated, and hydrogen bonds link the metal–organic framework with the uncoordinated water molecules. This study describes the first example of a three‐dimensional 3d–4f coordination polymer based on pyrazole‐3,5‐dicarboxylate and oxalate, and therefore demonstrates further the usefulness of pyrazoledicarboxylate as a versatile multidentate ligand for constructing heterometallic 3d–4f coordination polymers with interesting architectures. 相似文献

The molecule of the title compound {systematic name: di‐μ‐sulfido‐bis[diaqua(1,4,7,10,13,16‐hexaoxacyclooctadecane‐κ6O)barium(II)] bis[1,2‐benzisothiazol‐3(2H)‐one 1,1‐dioxide]}, [Ba2S2(C12H24O6)2(H2O)4](C7H5NO3S)2, lies on an inversion centre. The BaII atom encapsulated by the 18‐crown‐6 ring is coordinated by the six O atoms of the crown, two water O atoms and two bridging S atoms. The four‐membered ring composed of the BaII atoms and the bridging S atoms makes a dihedral angle of 67.1 (1)° with the crown‐ether ring. The aromatic ring system of the saccharin moiety is essentially planar. The packing is built up from layers of the molecules and is stabilized by three intermolecular O—H?O hydrogen bonds. 相似文献

The title compound, [Zn2(C9H4O6)2(C6H6N4)2], consists of two ZnII ions, two 5‐carboxybenzene‐1,3‐dicarboxylate (Hbtc2−) dianions and two 2,2′‐bi‐1H‐imidazole (bimz) molecules. The ZnII centre is coordinated by two carboxylate O atoms from two Hbtc2− ligands and by two imidazole N atoms of a bimz ligand, in a distorted tetrahedral coordination geometry. Two neighbouring ZnII ions are bridged by a pair of Hbtc2− ligands, forming a discrete binuclear [Zn2(Hbtc)2(bimz)2] structure lying across an inversion centre. Hydrogen bonds between carboxyl H atoms and carboxylate O atoms and between imidazole H atoms and carboxylate O atoms link the binuclear units. These binuclear units are further extended into a three‐dimensional supramolecular structure through extensive O—H...O and N—H...O hydrogen bonds. Moreover, the three‐dimensional nature of the crystal packing is reinforced by the π–π stacking. The title compound exhibits photoluminescence in the solid state, with an emission maximum at 415 nm. 相似文献

The title complex, [BaZn(C3H2O4)2(H2O)4]n, is polymeric, due to the connectivity brought about by each malonate dianion bonding to two different ZnII cations and two different BaII cations. The BaII cations, on crystallographic twofold axes, have slightly distorted square‐antiprismic coordination, with Ba—O distances ranging from 2.795 (2) to 2.848 (2) Å. The ZnII cations, which lie on crystallographic centres of symmetry, have distorted octahedral coordination, with Zn—O bonds in the range 2.0364 (19)–2.3248 (18) Å. The water molecules participate in extensive O—H⋯O hydrogen bonding. The structure comprises alternating layers along [100], with one type containing ZnII cations and malonate dianions, while the other is primarily composed of BaII cations and water molecules. 相似文献
