Bis(2,2'-bipyridine)(5,5'-imino-ditetra-zolato)cadmium(II) 2,2'-bipyridine hemisolvate monohydrate.

ABSTRACT

The title complex, [Cd(C(2)HN(9))(C(10)H(8)N(2))(2)]·0.5C(10)H(8)N(2)·H(2)O, was prepared under hydro-thermal reaction conditions. The asymmetric unit contains the cadmium complex, half a 2,2'-bipyridine solvent mol-ecule and a solvent water mol-ecule. The Cd(II) ion is coordinated by four N atoms from two 2,2'-bipyridine ligands and two N atoms from an HBTA(-) anion ligand [where H(2)BTA is N,N-bis-(1H-tetra-zol-5-yl)amine], forming an octa-hedral geometry. The complex is linked into a three-dimensional network by O-H⋯N and N-H⋯N hydrogen bonds and by the stacking inter-actions of rings, with distances of 3.5-3.7 Šbetween the atoms of two parallel 2,2'-bipyridine rings.
