چکیده
The title compound, [Zn(2)(C(6)H(4)N(5))(2)(H(2)O)(6)](CF(3)CO(2))(2)·H(2)O, was synthesized by hydro-thermal reaction of ZnBr(2), CF(3)COOH and 2-(2H-tetra-zol-5-yl)pyridine. The Zn(II) cation is coordinated by one N atom from the 5-(2-pyrid-yl)tetra-zolate anion, two N atoms from another 5-(2-pyrid-yl)tetra-zolate anion and three O atoms from three water mol-ecules in a distorted octa-hedral geometry. The tetra-zole ligands bridge the metal ions of the dimeric structure, and the dimers are located on crystallographic inversion centers. An inter-stitial solvent water mol-ecule is located on a crystallographic mirror plane, and the CF(3)COO(-) counter-anions are also not coordinated to the metal complex. The F atoms of the anions are disordered with the F atoms statistically distributed over two positions in a 0.56 (3)/0.44 (3) ratio. All the water H atoms are involved in O-H⋯N and O-H⋯O hydrogen bonds with uncoordinated water O atoms, carboxyl-ate O atoms and tetra-zole N atoms. The inter-actions link the mol-ecules into a three-dimensional network.

In the title complex, [Zn(2)(C(7)H(3)N(5)O(2))(2)(H(2)O)(6)], the 5-(5-carboxyl-ato-3-pyrid-yl)tetra-zolate ligand chelates the Zn(II) center through one pyridyl N and one tetra-zolate N atom, and uses another N atom to bridge to the second Zn atom, forming a centrosymmetric dinuclear unit. Three coordinated water mol-ecules complete the distorted octa-hedral geometry of the Zn(II) atom. O-H⋯O ...

In the title centrosymmetric dinuclear complex, [Cu(2)(C(15)H(11)BrN(2)O(3)S)(2)(C(2)H(6)OS)(2)], the Cu(II) ion is N,O-chelated by a dianionic ligand, monocoordinated by the sulfonamide N atom of a symmetry-related ligand and coordinated by an O atom from a dimethyl sulfoxide ligand, forming a distorted square-planar coordination geometry.
