Diaquabis[2,6-bis(4H-1,2,4-triazol-4-yl)pyridine-κN2]bis(selenocyanato-κN)cobalt(II)

Abstract

In the title compound, [Co(NCSe)2(C9H7N7)2(H2O)2], the Co2+ cation is coordinated by two seleno­cyanate anions, two 2,6-bis­(4H-1,2,4-triazol-4-yl)pyridine ligands and two water mol­ecules within a slightly distorted N4O2 octa­hedron. The asymmetric unit consists of one Co2+ cation, which is located on a center of inversion, as well as one seleno­cyanate anion, one 2,6-bis­(4H-1,2,4-triazol-4-yl)pyridine ligand and one water mol­ecule in general positions. Inter­molecular O—H⋯N hydrogen bonds join the complex mol­ecules into layers parallel to the bc plane. The layers are linked by C—H⋯N and C—H⋯Se hydrogen bonds into a three-dimensional supra­molecular architecture.
