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-HN hydrogen bonds join the complex molecules into layers parallel to the bc plane. The layers are linked by C-HN and C-HSe hydrogen bonds into a three-dimensional supramolecular architecture.
