In the title compound, [MnCl2(C6H6N4S2)(2)].CH3OH, the Mn-II ion is coordinated by two 2,2'-diamino-4,4'-bithia-zole ligands and two Cl- anions in cis positions to form a distorted octa-hedral coordination geometry. In the crystal structure, a three-dimensional supra-molecular structure involving hydrogen bonding and aromatic packing is observed.
