Bottom Line: The asymmetric unit consists of three crystallographically independent Co(II) cations, six thio-cyanate anions and six coordinating bpe ligands in general positions.Additionally, three non-coordin-ating bpe ligands are present in the asymmetric unit with two of them located on a center of inversion.The Co(II) cations are connected by the bpe ligands into layers parallel to the bc plane.

ABSTRACT
In the crystal structure of the title compound, [Co(NCS)(2)(C(12)H(10)N(2))(2)]·C(12)H(10)N(2), the Co(II) cations are octa-hedrally coordinated by two terminally N-bonded thio-cyanate anions and four 1,2-bis-(pyridin-4-yl)ethene (bpe) ligands. The asymmetric unit consists of three crystallographically independent Co(II) cations, six thio-cyanate anions and six coordinating bpe ligands in general positions. Additionally, three non-coordin-ating bpe ligands are present in the asymmetric unit with two of them located on a center of inversion. The Co(II) cations are connected by the bpe ligands into layers parallel to the bc plane. The crystal investigated was non-merohedrically twinned, with a fractional contribution of 0.261 (2) for the minor domain.
