Bis(2-amino-5-methyl-1,3,4-thiadiazole-κN 3)dichloridocobalt(II)

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).
