Article Abstract
In the title compound, [Zn(C(14)H(8)N(2)O(6))(H(2)O)(4)](n), the 2,2'-dihydr-oxy-5,5'-diazenediyldibenzoate ligand acts as a carboxyl-ate bridge, leading to the formation of a polymeric chain running along the [10] direction. The Zn(II) atom is hexa-coordinated in a distorted octa-hedral geometry by six O atoms [Zn-O = 2.055 (4)-2.132 (3) Å] from two carboxylate ligands and four water mol-ecules. The crystal packing is stabilized by inter-molecular O-H⋯O, O-H⋯N and C-H⋯O hydrogen bonds, and two π-π inter-actions. The centroid-centroid distances are 3.803 (16) and 3.804 (17) Å.

Reaction of Co(NCS) with 4-methyl-pyridine in water leads to the formation of single crystals of the title compound, [Co(NCS)(CHN)] . The asymmetric unit consists of two crystallographically independent thio-cyanate anions and two crystallographically independent 4-methyl-pyridine coligands in general positions, as well as of two different Co cations, of which one is located on a twofold rotational axis, whereas the second occupies a center of inversion. The methyl H atoms in both 4-methyl-pyridine ligands are disordered and were refined using a split model.

The asymmetric unit of the title compound, [Co(CBrO)(CHN)(HO)] or [Co(Brbdc)(im)(HO)] , comprises half of Co ion, tetra-bromo-benzene-dicarboxylate (Brbdc), imidazole (im) and a water mol-ecule. The Co ion exhibits a six-coordinated octa-hedral geometry with two oxygen atoms of the Brbdc ligand, two oxygen atoms of the water mol-ecules, and two nitro-gen atoms of the im ligands. The carboxyl-ate group is nearly perpendicular to the benzene ring and shows monodentate coordination to the Co ion.

In the title compound, di-phenyl-tin(IV) diiso-thio-cyanate, [Sn(NCS)(CH)] or PhSn(NCS), comparatively long tin-nitro-gen and short tin-sulfur bonds prove that the ambidentate iso-thio-cyanate ion acts as a bridge between two neighboring, octa-hedrally coordinated tin atoms. As a result, the mol-ecules lose their individuality in favor of a layered coordination polymer that represents a new type of mol-ecular inter-actions in the structural chemistry of diorganotin(IV) dihalides/pseudohalides. The tin atom is located on a center of inversion.
