Trans-Bis[2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole-κ(2) N (2),N (3)]bis-(methanol-κO)iron(II) bis-(perchlorate).

Abstract

The title compound, [Fe(C12H8N4S)2(CH3OH)2](ClO4)2, crystallized in the solvent-free form from a methanol solution. The FeII ion is located on a centre of inversion. The distorted N4O2 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.
