RESUMEN
The title compound, [Co(C(10)H(8)N(2))(3)](2)[V(4)O(12)]·11H(2)O, is composed of two symmetry-related cations containing octahedrally coordinated Co(II) ions, a centrosymmetric [V(4)O(12)](4-) anion with an eight-membered ring structure made up of four VO(4) tetrahedra, and 11 solvent water molecules. The Co(II) cations and vanadate anions are isolated and build cation and anion layers, respectively. In addition, the title compound exhibits a three-dimensional network through intra- and intermolecular hydrogen-bond interactions between water molecules and O atoms of the anions, and the crystal structure is stabilized mainly by hydrogen bonds.
RESUMEN
Poly[[(µ(3)-benzotriazole-5-carboxylato-κ(4)N(1):N(3):O,O')(1,4,8,9-tetraazatriphenylene-κ(2)N(8),N(9))zinc(II)] 0.25-hydrate], {[Zn(C(7)H(3)N(3)O(2))(C(14)H(8)N(4))]·0.25H(2)O}(n), exhibits a two-dimensional layer structure in which the asymmetric unit contains one Zn(II) centre, one 1,4,8,9-tetraazatriphenylene (TATP) ligand, one benzotriazole-5-carboxylate (btca) ligand and 0.25 solvent water molecules. Each Zn(II) ion is six-coordinated and surrounded by four N atoms from two different btca ligands and one chelating TATP ligand, and by two O atoms from a third btca ligand, to furnish a distorted octahedral geometry. The infinite connection of the metal ions and ligands forms a two-dimensional wave-like (6,3) layer structure. Adjacent layers are connected by C-H...N hydrogen bonds. The solvent water molecules are located in partially occupied sites between parallel pairs of inversion-related TATP ligands that belong to two separate layers.
