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

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 N4O2octahedron. 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 thebcplane. The layers are linked by C—H...N and C—H...Se hydrogen bonds into a three-dimensional supramolecular architecture.
