Poly[tetra-kis-(seleno-cyanato-κN)bis-(methanol-κO)tris-(μ-pyrimidine-κN:N')dicobalt(II)].

In the title compound, [Co(2)(NCSe)(4)(C(4)H(4)N(2))(3)(CH(3)OH)(2)](n), the Co(II) ion is coordinated by three N-bonded pyrimidine ligands, two N-bonded seleno-cyanate anions and one O-bonded methanol mol-ecule in an octa-hedral coordination mode. The asymmetric unit consists of one Co(II) ion, one pyrimidine ligand, two seleno-cyanate anions and one methanol mol-ecule in general positions as well as one pyrimidine ligand located around a twofold rotation axis. In the crystal structure, the pyrimidine ligands bridge [Co(CNSe)(2)(CH(3)OH)] units into zigzag-like chains, which are further connected by pyrimidine ligands into layers parallel to (010).
