An interpenetrating primitive cubic net formed by hydrogen bonds and coordination bonds in catena-poly[[bis(methanol-kappaO)bis(thiocyanato-kappaN)iron(II)]-mu-1,2-bis(4-pyridylmethylene)hydrazine-kappa2N:N'].
In the title compound, [Fe(NCS)(2)(C(12)H(10)N(4))(CH(4)O)(2)](n), at 153 (2) K, the Fe atom is located on an inversion centre, as is the centre of the N-N bond in the ligand molecule. The structure contains a one-dimensional coordination polymer with an Fe...Fe distance of 15.866 (7) A and can be described as two interpenetrating six-connected primitive cubic (pcu) three-dimensional networks when additional intermolecular O-H...S hydrogen bonds are taken into account. The compound is not isostructural with the corresponding Mn(II) compound as they differ in the rotation around the M-O bond by 90 degrees , giving rise to completely different hydrogen-bond patterns. This study demonstrates the impact of conformational differences on the final supramolecular arrangement.
