Abstract

In the crystal structure of the title compound, [Co(NCS)2(C12H10N2)2]·C12H10N2, the CoII cations are octa­hedrally coordinated by two terminally N-bonded thio­cyanate anions and four 1,2-bis­(pyridin-4-yl)ethene (bpe) ligands. The asymmetric unit consists of three crystallographically independent CoII cations, six thio­cyanate anions and six coordinating bpe ligands in general positions. Additionally, three non-coordin­ating bpe ligands are present in the asymmetric unit with two of them located on a center of inversion. The CoII 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.
