trans-Bis[2,5-bis­(pyridin-2-yl)-1,3,4-thia­diazole-κ(2) N (2),N (3)]bis­(methanol-κO)iron(II) bis­(perchlorate)

The title compound, [Fe(C(12)H(8)N(4)S)(2)(CH(3)OH)(2)](ClO(4))(2), crystallized in the solvent-free form from a methanol solution. The Fe(II) ion is located on a centre of inversion. The distorted N(4)O(2) octa­hedral coordination geometry is formed by two N,N′-chelating equatorial 2,5-bis­(pyridin-2-yl)-1,3,4-thia­diazole ligands and axially coordinating methanol coligands, resulting in the mononuclear trans-(N (2),N (3),O)(2) coordination mode. The methanol co-ligand is involved in a hydrogen bond to the perchlorate counter-ion.
