Poly[μ₇-sulfanediyldiacetato-disilver(I)]

X.-M. Hao, G. Chen, C.-S. Gu and J.-W. Liu

In the title coordination polymer, each Ag^I cation has a distorted tetrahedral geometry coordinated by three of the four carboxylate O atoms and the S atom from symmetry-related sulfanediyldiacetate ligands. The bridging sulfanediyldiacetate groups lead to a two-dimensional layer structure and the layers are interconnected via Ag—S bonds.

A three-dimensional Cu–Na heteronuclear coordination polymer based on iminodiacetic acid

Y.-H. Wang, R.-F. Song and F. Jiang

In a novel Cu–Na heteronuclear three-dimensional coordination polymer, the carboxylate groups of iminodiacetate (ida) ligands act as bridges and connect [Cu(ida)] and [Cu(ida)₂] building blocks in a 2:1 ratio, forming two-dimensional arrays. These layers are interconnected into a three-dimensional structure by sodium ions.

A fivefold interpenetrating diamondoid framework constructed by flexible dipyridyl and dicarboxylate ligands

J.-F. Wang, W.-J. Guo and F.-Z. Deng

In a novel three-dimensional Cd^II complex prepared by hydrothermal assembly of Cd(NO₃)₂·4H₂O, 1,4-bis[2-(pyridin-4-yl)ethenyl]benzene and 2,2′-(1,4-phenylene)diacetic acid, each Cd^II centre is located in a distorted pentagonal bipyramidal coordination environment. The three-dimensional net can be regarded as a diamondoid network by treating the Cd^II atoms as nodes and the benzene and diacetic acid ligands as linkers.

A three-dimensional chiral crystal structure constructed from a chiral triazolate ligand showing an SrSi₂ topology: poly[bis(μ₃-3,5-diethyl-1,2,4-triazolato-κ³N¹:N²:N⁴)trisilver nitrate]

F. Jiang, L. Dai, Y. Shi and Z. Wang

A metal–organic framework (MOF) is reported in which an Ag^I cation is coordinated by two N atoms from two different 3,5-diethyl-1,2,4-triazolate ligands in a linear configuration. Each Ag^I cation is then connected to two adjacent Ag^I cations via a μ₃-N¹:N²:N⁴-triazolate ligand.

Poly[[μ-(1-azaniumylethane-1,1-diyl)bis(hydrogen phosphonato)]sodium]: a powder X-ray diffraction study

M. Rukiah and T. Assaad

The central Na⁺ cation exhibits distorted octahedral coordination geometry involving two deprotonated O atoms, two hydroxy O atoms and two double-bonded O atoms of the bisphosphonate anion. Pairs of sodium-centred octahedra share edges and the pairs are in turn connected to each other by the biphosphonate anion to form a two-dimensional network parallel to the (001) plane.

A three-dimensional polymeric potassium complex incorporating bridging water molecules and 2,4-dicarboxy-5-sulfonatobenzoate ligands forms a one-dimensional inorganic chain with cage-like K₄(SO₃)₂ repeat units. The chains are bridged by carboxylic acid groups to form a two-dimensional layer, and these layers are further linked by carboyxlate groups and benzene rings to generate a three-dimensional framework.

The crystal structures of bis(4-methylanilinium) and bis(4-iodoanilinium) pentamolybdates were determined using laboratory X-ray data and refined by total energy minimization methods. The obtained structures present alternating organic cation and inorganic polyanion layers bound by weak bonding (apart from ionic interactions).

Coordination polymeric structures in the sodium salt of 4-chloro-3-nitrobenzoic acid and the sodium and potassium salts of 4-nitroanthranilic acid

G. Smith

The hydrated sodium salt of 4-chloro-3-nitrobenzoic acid and the hydrated sodium and potassium salts of 2-amino-4-nitrobenzoic acid are stabilized by intra- and intermolecular hydrogen bonding and strong π–π ring interactions. Na centres are linked through centrosymmetric four-membered duplex water bridges and through 18-membered duplex head-to-tail ligand bridges. Similar centrosymmetric bridges are found in the potassium salt.
