Two new cobalt(III) complexes with pyridoxal [3-hydroxy-5-(hydroxymethyl)-2-methylpyridine-4-carbaldehyde] and pyruvic acid thiosemicarbazones (H2L and H2pt)[Co(HL)2]Cl·EtOH 1 and [Co(Hpt)(pt)]2 respectively, have been synthesized and characterized using single-crystal X-ray diffraction and IR and CD spectroscopic methods. The structure of 2-thio-6-azathymine [6-methyl-3-thioxo-1,2,4-triazin-5-(2H
