Catena-Poly[[diaquazinc(II)]-?-trans-4,4'-diazenediyldibenzoato-?O,O':O'',O'''].

ABSTRACT: The title compound, [Zn(C(14)H(8)N(2)O(4))(H(2)O)(2)](n), consists of zigzag chains of Zn atoms bridged by azobenzene-4,4'-dicarboxyl-ate ligands. The Zn(II) atom, lying on a twofold rotation axis, is coordinated by four O atoms from the carboxyl-ate groups and two water mol-ecules, giving rise to a considerably distorted octa-hedral coordination envionment. The ligand lies on an inversion center. In the crystal structure, ?-? inter-actions between the ligands [inter-planar distance = 3.527?(3)?Å] assemble the chains into a sheet-like structure. O-H?O hydrogen bonds between the coordinated water mol-ecules and carboxyl-ate O atoms connect the sheets into a three-dimensional network.

Project description:In the title compound, [Mo(2)(C(7)F(5)O(2))(4)(C(10)H(8)N(2))](n), the mol-ecule forms a paddle-wheel-type structure. Each Mo(2) (4+) unit is equatorially coordinated by four pentafluoro-benzoate groups, while the axial positions are occupied by two 4,4'-bipyridine mol-ecules. The Mo-Mo bond length of 2.1227 (4) Å is representative of a dimolybdenum quadruple bond. An infinite linear chain parallel to [110] is formed by the Mo(2) (4+) unit coordinating axially to the two N atoms of the 4,4'-bipyridine ligand [Mo-N = 2.594 (2) Å]. The crystal packing shows mol-ecules linked together into a three-dimensional network via Mo-N coordination inter-actions and weak π-π stacking inter-actions between perfluoro-phenyl rings [centroid-centroid distance = 3.7280 (3) Å and centroid-to-plane distance = 3.6103 (12) Å between two penta-fluoro-phenyl rings].

Project description:In the title coordination polymer, [Co(C(14)H(16)O(6))(H(2)O)(2)](n), the Co(II) ion, situated on a twofold rotation axis, is coordinated by four O atoms from two 4,4'-[1,4-phenyl-enebis(-oxy)]dibutano-ate (L) ligands and two water mol-ecules in a highly distorted octa-hedral geometry. Each L ligand is situated on an inversion center and bridges two Co(II) atoms, forming a zigzag polymeric chain propagating in [10]. Inter-molecular O-H⋯O hydrogen bonds further consolidate the crystal packing.

Project description:The title compound, {[Co(C(2)H(5)COO)(2)(H(2)O)]·H(2)O}(n), was synthesized by the reaction of cobalt(II) carbonate hydrate with aqueous propionic acid. The structure consists of polymeric infinite linear chains with composition [Co(C(2)H(5)COO)(4/2)(H(2)O)(2/2)](∞) running along [010].

The Co(2+) ion is six-coordinated in a strongly distorted octa-hedral geometry. The chains are connected to each other by a network of O-H⋯O hydrogen bonds involving solvent water mol-ecules.

Project description:Single crystals of the title compound, {Na(4)[Mo(VI)O(2)(SO(4))(3)]}(n), were grown from a melt of MoO(3) and Na(2)SO(4) in Na(2)S(2)O(7). In contrast to the structure of the isoformular K compound, K(4)[Mo(VI)O(2)(SO(4))(3)], with its monomeric anion, this sodium analogue contains a polymeric anion of the type {[Mo(VI)O(2)(SO(4))(2)-μ-(SO(4))](4-)}(n). The Mo(VI) cations, surrounded by two tightly bonded O atoms and four O atoms of one bridging and two terminal sulfato ligands, form zigzag chains parallel to [100]. All four Na(+) cations are situated between the anionic chains and have distorted octa-hedral coordination spheres.

Project description:The 4,4'-bipyridine heterocycle in the polymeric title compound, [Cd(C(16)H(13)O(3))(2)(C(10)H(8)N(2))(H(2)O)](n), links adjacent Cd(II) ions into a chain running along the c axis. The Cd atom, which lies on a twofold rotation axis, is chelated by the carboxyl-ate unit and exists in a seven-coordinate penta-gonal-bipyramidal geometry. The apical sites are occupied by N atoms. The water mol-ecule also lies on the twofold rotation axis. The methyl substituent of the propano-ate group is disordered over two positions in a 1:1 ratio. O-H⋯O hydrogen bonding between water molecules and adjacent carboxylate O atoms is observed.
