An interpenetrating primitive cubic net formed by hydrogen bonds and coordination bonds in catena-poly[[bis(methanol-κO)bis(thiocyanato-κN)iron(II)]-μ-1,2-bis(4-pyridylmethylene)hydrazine-κ2N:N']

In the title compound, [Fe(NCS)2(C12H10N4)(CH4O)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) Å 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 MnII compound as they differ in the rotation around the M-O bond by 90°, giving rise to completely different hydrogen-bond patterns. This study demonstrates the impact of conformational differences on the final supramolecular arrangement.
