چکیده
In the title spiro compound, C(29)H(24)N(4)S, the quinoxaline and thia-diazole ring systems share a common C atom; their mean planes are aligned at 87.0 (1)° in one mol-ecule and at 84.1 (1)° in the other independent mol-ecule. The thia-zole ring possesses two aromatic ring substituents and is roughly coplanar with these rings [the dihedral angles between the thia-diazole and phenyl rings are 10.7 (1) and 11.7 (1)° in one mol-ecule, and 16.8 (1) and 17.7 (1)° in the other]. The aromatic ring of the benzyl unit of one mol-ecule is disordered over two orientations in a 1:1 ratio.

In the monomeric title complex, [CoCl(2)(C(3)H(5)N(3)S)(2)], the Co(II) atom is tetra-coordinated by two chloride anions and two N atoms from two monodentate 2-amino-5-methyl-1,3,4-thia-diazole ligands, giving a slightly distorted tetra-hedral stereochemistry [bond angle range about Co = 105.16 (12)-112.50 (10)°]. In the complex, the dihedral angle between the 1,3,4-thia-diazole planes in the t...

In the crystal structure of the title compound, C(5)H(3)Cl(3)N(4)S, two mol-ecules related by a centre of symmetry demonstrate extremely short inter-molecular S⋯N contacts of 2.783 (2) Å. The crystal packing also exhibits π-π inter-actions indicated by a short distance of 3.340 (1) Å between the centroids of the triazole rings of neighbouring mol-ecules.
