A new ligand, pyridoxilidene Girard-T hydrazone, [H3L]Cl-2 . 2H(2)O, and its octahedral cobalt(III) complexes [Co(HL) (NO2)(3)] . H2O (1) and [Co(HL)(2)](PF6)(3) (2) were synthesized. The X-ray analysis of (1) showed that the complex has a mer-octahedral configuration formed by coordination of the tridentate ONO neutral Schiff-base molecule and three monodentate N-bonded NO2 groups. Hydrogen bonds and intermolecular interactions for this complex are discussed. Complex (2) also has a mer-octahedral configuration. The ligand and complexes were characterized by elemental analysis, conductometric and magnetochemical measurements, IR and UV-Visible, H-1 and C-13 NMR spectra. (C) 2004 Published by Elsevier B.V.
