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

In the title compound, [Co(NCSe)(2)(C9H7N7)(2)(H2O)(2)], the Co-2 vertical bar 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 center dot center dot center dot N hydrogen bonds join the complex molecules into layers parallel to the bc plane. The layers are linked by C-H center dot center dot center dot N and C-H center dot center dot center dot Se hydrogen bonds into a three-dimensional supramolecular architecture.
