Abstract

In the monomeric title complex, [CoCl2(C3H5N3S)2], the CoII atom is tetra­coordinated by two chloride anions and two N atoms from two monodentate 2-amino-5-methyl-1,3,4-thia­diazole ligands, giving a slightly distorted tetra­hedral stereochemistry [bond angle range about Co = 105.16 (12)–112.50 (10)°]. In the complex, the dihedral angle between the 1,3,4-thia­diazole planes in the two ligands is 72.8 (1)°. There are two intra­molecular N—H⋯Cl inter­actions in the complex unit, while in the crystal, inter­molecular N—H⋯N and N—H⋯Cl hydrogen bonds link these units into a two-dimensional layered structure parallel to (011).
