The synthesis, characterization and thermogravimetric studies of [N,N'-cis-1,2-cyclohexylene bis(salicylideneaminato)]cobalt(II), [Co(II)(c-Salcn)], and [N,N'-(+/-)-trans-1,2-cyclohexylene bis(salicylideneaminato)]cobalt(II), [Co(II)(t-Salcn)l are reported. The free ligands were characterized by elemental analyses, melting points, IR, electronic, and H-1 and C-13 NMR spectra. The cobalt(II) complexes were characterized by elemental analyses, melting points, IR and electronic spectra. The IR and electronic spectra of the free ligands and the complexes are compared and discussed. The thermogravimetric data for both isomers showed two-step decomposition, but the trans isomer was less stable than the cis. Different cobalt oxides are formed as the final decomposition product depending on the atmosphere used, nitrogen or air. (C) 2001 Elsevier Science B.V. All rights reserved.
