Bis(2,2'-bipyridine)(5,5'-iminoditetrazolato)cadmium(II) 2,2'-bipyridine hemisolvate monohydrate

J.-M. Lin, Y.-F. Guan and W. Dong

Abstract: The title complex, [Cd(C₂HN₉)(C₁₀H₈N₂)₂]·0.5C₁₀H₈N₂·H₂O, was prepared under hydrothermal reaction conditions. The asymmetric unit contains the cadmium complex, half a 2,2'-bipyridine solvent molecule and a solvent water molecule. 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 H₂BTA is N,N-bis(1H-tetrazol-5-yl)amine], forming an octahedral geometry. The complex is linked into a three-dimensional network by O-HN and N-HN hydrogen bonds and by the stacking interactions of rings, with distances of 3.5-3.7 Å between the atoms of two parallel 2,2'-bipyridine rings.
