Bis(2,2′-bipyridine)[5,5′-iminobis(tetrazolato)]nickel(II) hexahydrate

Abstract

The title complex, [Ni(C2H1N9)(C10H8N2)2]·6H2O, was prepared under hydro­thermal reaction conditions. The asymmetric unit contains the nickel complex and six solvent water mol­ecules. The NiII ion is coordinated in a distorted octa­hedral geometry defined by four N atoms from two 2,2′-bipyridine ligands and two N atoms from the 5,5′-imino­bis(tetra­zolate) (BTA2−) anions. In the crystal structure, an extensive range of O—H⋯N and O—H⋯O hydrogen bonds links the complex and the water mol­ecules into a three-dimensional network.
