catena-Poly[[diaqua­bis(thio­cyanato-κN)cobalt(II)]-μ-4,4′-bipyridine-κ(2) N:N′] 4,4′-bipyridine solvate]

In the title complex, {[Co(NCS)(2)(C(10)H(8)N(2))(H(2)O)(2)]·C(10)H(8)N(2)}(n), the Co(II) ion is located on an inversion centre and is coordinated by two N atoms from the two 4,4′-bipyridine ligands, two O atoms from the water mol­ecule, and two N atoms from two isothio­cyanate ions in a distorted octa­hedral environment. In the crystal, the coordinated water mol­ecules, isothio­cyanate ions and solvent 4,4′-bipyridine mol­ecules are linked by O—H⋯S and O—H⋯N hydrogen bonds into layers parallel to the ab plane.
