In the title compound, catena‐poly[[[triaquacopper(II)]‐μ‐acetylenedicarboxylato‐κ2O:O′′] hydrate], {[Cu(C4O4)(H2O)3]·H2O}n, the CuII ion is coordinated by two monodentate carboxylate groups in trans positions and three water molecules, thus forming a fivefold coordination polyhedron that can be described as a distorted square pyramid. All atoms are located on general sites. The polyhedra are connected by bifunctional acetylenedicarboxylate ligands, to form almost linear chains parallel to [001]. Hydrogen bonds involving the non‐coordinated water molecule connect these chains to form a three‐dimensional framework. 相似文献

In catena‐poly[[[triaquacadmium(II)]‐μ‐acetylenedicarboxylato‐κ4O,O′:O′′,O′′′] hydrate], {[Cd(C4O4)(H2O)3]·H2O}n, the CdII atom is coordinated by two bidentate carboxylate groups and three water molecules, thus forming a sevenfold coordination polyhedron with all atoms located on general sites. These polyhedra are connected by the bifunctional acetylenedicarboxylate ligands, forming zigzag chains running parallel to [120]. Hydrogen bonds, which involve the non‐coordinated water molecule, connect these chains to form a three‐dimensional framework. 相似文献

The asymmetric unit of the title one‐dimensional coordination polymer, catena‐poly[[μ‐pyridine‐2,3‐dicarboxylato‐1κO:2κ2N,O′‐bis[diaquacobalt(II)]]‐μ‐pyridine‐2,3‐dicarboxylato‐1κ2N,O:2κO′:1′κO′], [Co(C7H3NO4)(H2O)2]n, is composed of a cobalt(II) ion, a pyridine‐2,3‐dicarboxylate dianion and two water molecules. The polymer has a zigzag structure consisting of a chain of edge‐fused rings, and the polymer chains are linked by O—H⃛O hydrogen bonds into a three‐dimensional framework. 相似文献

In catena‐poly[[(di‐2‐pyridylamine‐κ2N,N′)silver(I)]‐μ‐nicotinato‐κ2N:O], [Ag(C6H4NO2)(C10H9N3)]n, the AgI atom is tetracoordinated by two N atoms from the di‐2‐pyridylamine (BPA) ligand [Ag—N = 2.3785 (18) and 2.3298 (18) Å] and by one N atom and one carboxylate O atom from nicotinate ligands [Ag—N = 2.2827 (15) Å and Ag—O = 2.3636 (14) Å]. Bridging by nicotinate N and O atoms generates a polymeric chain structure, which extends along [100]. The carboxyl O atom not bonded to the Ag atom takes part in an intrachain C—H⋯O hydrogen bond, further stabilizing the chain. Pairs of chains are linked by N—H⋯O hydrogen bonds to generate ribbons. There are no π–π interactions in this complex. In catena‐poly[[(di‐2‐pyridylamine‐κ2N,N′)silver(I)]‐μ‐2,6‐dihydroxybenzoato‐κ2O1:O2], [Ag(C7H5O4)(C10H9N3)]n, the AgI atom has a distorted tetrahedral coordination, with three strong bonds to two pyridine N atoms from the BPA ligand [Ag—N = 2.286 (5) and 2.320 (5) Å] and to one carboxylate O atom from the 2,6‐dihydroxybenzoate ligand [Ag—O = 2.222 (4) Å]; the fourth, weaker, Ag‐atom coordination is to one of the phenol O atoms [Ag⋯O = 2.703 (4) Å] of an adjacent moiety, and this interaction generates a polymeric chain along [100]. Pairs of chains are linked about inversion centers by N—H⋯O hydrogen bonds to form ribbons, within which there are π–π interactions. The ribbons are linked about inversion centers by pairs of C—H⋯O hydrogen bonds and additional π–π interactions between inversion‐related pairs of 2,6‐dihydroxybenzoate ligands to generate a three‐dimensional network. 相似文献

Extensive intermolecular hydrogen‐bonding interactions involving coordinated and uncoordinated water molecules and the carboxyl O atoms of the dipicolinate ligand, as well as a stacking interaction involving the phenanthroline rings, are observed in the crystal structure. 相似文献

catena‐Poly[dicyclohexylammonium [tributyltin‐μ‐(4‐oxo‐4H‐pyran‐2,6‐dicarboxylato‐O2:O6)]], (C12H24N)[Sn(C7H2O6)(C4H9)3], consists of 4‐oxo‐4H‐pyran‐2,6‐dicarboxylato groups that axially link adjacent tributyltin units into a linear polyanionic chain. The ammonium counter‐ions surround the chain, and each cation forms a pair of hydrogen bonds to the double‐bond carbonyl O atoms of the same dianionic group. The chain propagates in a zigzag manner along the c axis of the monoclinic cell. In catena‐poly[methyl(phenyl)ammonium [tributyltin‐μ‐(pyridine‐2,6‐dicarboxylato‐O2:O6)]], (C7H10N)[Sn(C7H3NO4)(C4H9)3], the pyridine‐2,6‐dicarboxylato groups also link the tributyltin groups into a chain, but the hydrogen‐bonded chain propagates linearly on the ac face of the monoclinic cell. 相似文献

Structural determinations of the magnesium(II) and barium(II) salts of pyromellitic acid (benzene‐1,2,4,5‐tetracarboxylic acid) are presented. Hexaaquamagnesium(II) benzene‐1,2,4,5‐tetracarboxylate(2−), [Mg(H2O)6](C10H4O8), (I), and pentaaqua[benzene‐1,2,4,5‐tetracarboxylato(2−)]barium(II), [Ba(C10H4O8)(H2O)5], (II), are both centrosymmetric and both possess a 1:1 metal–ligand ratio, but the two structures are found to differ in that the magnesium salt contains a hexaaqua cation and possesses only hydrogen‐bonding interactions between cations and anions, while the barium salt exhibits coordination of the carboxylate ligand to the nine‐coordinate metal centre. In (I), both ions sit on a 2/m site symmetry, and in (II), the cation and anion are located on m and i site symmetries, respectively. 相似文献

Voids are filled by the corresponding counter‐anions and solvate molecules, defining a complex three‐dimensional network surrounding them. In both structures, the cationic chains evolve around a set of twofold axes passing through the NiII ions and bisecting the aromatic amines through their N (and their opposite C) atoms. 相似文献

In title (hydrated) trans‐diaquabis(propane‐1,3‐diamine‐κ2N,N′)copper(II) dithionate, [Cu(C3H10N2)2(H2O)2](S2O6) or [{H2N(CH2)3NH2}2Cu(OH2)2](S2O6), both ions have imposed 2/m symmetry. The `axial' anion components are displaced by a pair of water ligands [Cu—O = 2.439 (3) Å], the shorter Cu—O distance being compensated by the lengthened Cu—N distance [2.0443 (18), cf. 2.0100 (13) and 2.0122 (16) Å]. 相似文献

Each La3+ ion in the title complex, tetra‐μ‐2‐fluorobenzoato‐κ10O:O′;O:O,O′;O:O′;O,O′:O′‐bis[aqua(4,4′‐bipyridine‐κN)(2‐fluorobenzoato‐κO)lanthanum(II)], [La(C7H4FO2)6(C10H8N2)2(H2O)2], is coordinated by six O atoms from the carboxylate groups of five 2‐fluorobenzoate ligands, one O atom from a water molecule and one N atom from a 4,4′‐bipyridine molecule, thus forming a dimeric molecule. An infinite one‐dimensional dimeric supramolecular chain is formed via intermolecular hydrogen bonds. 相似文献

A new polymeric copper complex, viz.catena‐poly[[[μ‐N,N′‐bis(3‐aminopropyl)oxamidato‐κ6N,N′,O:N′′,N′′′,O′]dicopper(II)]‐di‐μ‐dicyanamido‐1:1′κ2N1:N5;2:2′κ2N1:N5], [Cu2(C8H16N4O2)(C2N3)2]n or [Cu(oxpn)0.5{N(CN)2}]n [where H2oxpn is N,N′‐bis(3‐aminopropyl)oxamide], has been synthesized by the reaction of Cu(oxpn), [Cu(ClO4)2]·6H2O and NaN3. In the crystal structure, the Cu atom is five‐coordinate and has a square‐pyrimidal (SP) configuration. In the polymer, dicyanamide (dca−) groups link CuII cations in a μ‐1,5‐bridging mode, generating novel ladders in which each step is composed of dimeric [Cu2(oxpn)]2+ cations. Abundant hydrogen bonds connect the polymer ladders into a two‐dimensional network structure. 相似文献

The title diphenylcarbene porphyrin complex (diphenylcarbenyl‐κC)(methanol‐κO)(5,10,15,20‐tetra‐p‐tolylporphyrinato‐κ4N)ruthenium(II) methanol solvate, [Ru(C13H10)(C48H36N4)(CH4O)]·CH4O, has a six‐coordinate Ru atom with a methanol molecule as the second axial ligand. The carbene fragment is slightly distorted from an ideal sp2 configuration, with a C(phenyl)—C(carbene)—C(phenyl) angle of 112.2 (3)°. The Ru—C bond length of 1.845 (3) Å is comparable with other carbene complexes. The two phenyl rings of the carbene ligand are perpendicular to the carbene plane. Methanol solvate molecules link the methanol ligands of adjacent porphyrin complexes via hydrogen bonds. 相似文献

The title compound, poly[[aquazinc(II)]‐μ‐benzene‐1,3‐dicarboxylato‐O1:O1′:O2], [Zn(C8H4O4)(H2O)]n, forms a metal–organic coordination network that consists of tetrahedral Zn atoms bonded to one water molecule and three carboxylate groups. Isophthalate groups bridge the four‐coordinate Zn centers to generate two‐dimensional architectures in the ac plane. These planar zinc isophthalate motifs are linked by infinite C=O?H—O—H interactions along the a axis to form a chiral framework. The observed polar structural pattern originates due to the distorted tetrahedral Zn centers [O—Zn—O 100.7 (2)–136.0 (1)°] and the alignment of the water molecules. Bridging isophthalate groups align to form approximate centrosymmetric motifs. 相似文献

The title cadmium(II) polymer, catena‐poly[[[bis(4‐aminopyridine‐κN)aquacadmium(II)]‐μ‐1,4‐phenylenediacetato‐κ4O,O′:O′′,O′′′] dihydrate], {[Cd(C10H8O4)(C5H6N2)2(H2O)]·2H2O}n, comprises one‐dimensional wave‐like chains, in which the Cd atom is coordinated by 1,4‐phenylenediacetate and 4‐aminopyridine molecules. The 1,4‐phenylenediacetate ligands lie about inversion centres. Extensive hydrogen‐bonding interactions between the chains lead to a three‐dimensional structure.

The title compound, [Ca(C16H12O4)(H2O)6]·H2O, adopts a conformation about the central C—C bond that places the two carboxylate groups in an anti orientation. The crystal consists of layers of two‐dimensional arrays of 2,3‐diphenylsuccinate dianions which are linked by bridging Ca2+ cations. The unit cell contains two Ca2+ cations in an unusual four‐membered Ca—O—Ca—O ring in which the bridging O atoms belong to water molecules rather than carboxylates, i.e. poly[[[di‐μ‐aqua‐bis[pentaaquacalcium(II)]]‐μ‐(meso‐2,3‐diphenylsuccinato‐O:O′)] succinate dihydrate]. 相似文献

The one‐dimensional chain catena‐poly[[aqua(2,2′:6′,2′′‐terpyridyl‐κ3N)nickel(II)]‐μ‐cyano‐κ2N:C‐[bis(cyano‐κC)nickelate(II)]‐μ‐cyano‐κ2C:N], [Ni(terpy)(H2O)]‐trans‐[Ni‐μ‐(CN)2‐(CN)2]n or [Ni2(CN)4(C15H11N3)(H2O)], consists of infinite linear chains along the crystallographic [10] direction. The chains are composed of two distinct types of nickel ions, paramagnetic octahedral [Ni(terpy)(H2O)]2+ cations (with twofold crystallographic symmetry) and diamagnetic planar [Ni(CN)4]2? anions (with the Ni atom on an inversion center). The [Ni(CN)4]2? units act as bidentate ligands bridging through two trans cyano groups thus giving rise to a new example of a trans–trans chain among planar tetracyanonickelate complexes. The coordination geometry of the planar nickel unit is typical of slightly distorted octahedral nickel(II) complexes, but for the [Ni(CN)4]2? units, the geometry deviates from a planar configuration due to steric interactions with the terpyridine ligands. 相似文献

The title complexes, trans‐diaquabis(quinoline‐2‐carboxylato‐κ2N,O)cobalt(II)–water–methanol (1/2/2), [Co(C10H6NO2)2(H2O)2]·2CH4O·2H2O, and trans‐diaquabis(quinoline‐2‐carboxylato‐κ2N,O)nickel(II)–water–methanol (1/2/2), [Ni(C10H6NO2)2(H2O)2]·2CH4O·2H2O, are isomorphous and contain CoII and NiII ions at centers of inversion. Both complexes have the same distorted octahedral coordination geometry, and each metal ion is coordinated by two quinoline N atoms, two carboxylate O atoms and two water O atoms. The quinoline‐2‐carboxylate ligands lie in trans positions with respect to one another, forming the equatorial plane, with the two water ligands occupying the axial positions. The complex molecules are linked together by hydrogen bonding involving a series of ring patterns which include the uncoordinated water and methanol molecules. 相似文献

The title compound, [Pt(C6H10NO2)(C5H14N2)]2(SO4), crystallizes with two cations in the asymmetric unit. The two complex cations, which have a square‐planar PtII coordination, are chemically identical but differ slightly in the conformations of their amine groups. A neutral complex, viz. (2,2‐dimethyl‐1,3‐propanediamine‐κ2N,N′)bis(2‐piperidinecarboxylato‐κN)platinum(II), is shown to form in solution and to change rapidly into the title compound. 相似文献
