RESUMO
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 = 105.16â (12)-112.50â (10)°]. In the complex, the dihedral angle between the 1,3,4-thia-diazole planes in the two ligands is 72.8â (1)°. There are two intra-molecular N-Hâ¯Cl inter-actions in the complex unit, while in the crystal, inter-molecular N-Hâ¯N and N-Hâ¯Cl hydrogen bonds link these units into a two-dimensional layered structure parallel to (011).
RESUMO
In the mononuclear title complex, [Cu(C(11)H(7)N(6))(2)], the Cu(II) atom lies on a crystallographic inversion centre and is coordinated by four N atoms from two bidentate chelate monoanionic 3-(pyrazin-2-yl)-5-(pyridin-2-yl-1,2,4-triazol-1-ido ligands, two from the triazolide rings [Cu-N = 1.969â (2)â Å] and two from the pyridine rings [Cu-N = 2.027â (2)â Å], giving a slightly distorted square-planar geometry.
