چکیده
The title compound, [Fe(C12H8N4S)2(CH3OH)2](ClO4)2, crystallized in the solvent-free form from a methanol solution. The Fe(II) ion is located on a centre of inversion. The distorted N4O2 octa-hedral coordination geometry is formed by two N,N'-chelating equatorial 2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole 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.

The mononuclear title complex, [Cu(SCN)2(C12H8N4S)2], was obtained by the reaction of 2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole and potassium thio-cyanate with copper(II) chloride dihydrate. The copper cation lies on an inversion centre and displays an elongated octa-hedral coordination geometry. The equatorial positions are occupied by the N atoms of two 2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazo...
