Poly[[bis­[μ(2)-1,2-bis­(pyridin-4-yl)ethene-κ(2) N:N′]bis­(thio­cyanato-κN)cobalt(II)] 1,2-bis­(pyridin-4-yl)ethene monosolvate dihydrate]

The asymmetric unit of the title compound, {[Co(NCS)(2)(C(12)H(10)N(2))(2)]·C(12)H(10)N(2)·2H(2)O}(n), consists of two independent Co(II) cations, four distinct thio­cyanate anions, six 1,2-bis­(pyridin-4-yl)ethene (4-bpe) mol­ecules and four lattice water mol­ecules. The Co(II) cations are each coordinated by two N-bonded thio­cyanate anions and four 4-bpe ligands within a slightly distorted CoN(6) octa­hedron. The two independent Co(II) cations are linked by the 4-bpe ligands into two distinct layers, parallel to the ac and bc planes, that inter­penetrate. From this arrangement, channels are formed in which non-coordinated 4-bpe and lattice water mol­ecules are hydrogen-bonded into chains that elongate in the c-axis direction.
