| Abstract: | Different nitrogen donor ligands (pyridine, piperidine, quinoline, iso-quinoline, triazole, indole, benzimidazole, benzotriazole, carbazole) react with Co(SCN)2 and dimethylglyoxime (DH2) in ethanolic medium in presence of air to form a number of new Co(III) complexes of the type trans-[Co(DH)2(L)(SCN)], which are characterised on the basis of electronic and IR spectra NMR, (1H and 13C) spectra, thermogravimetric (TG-DT) analysis and conductance measurements. The thiocyanate group is S-bonded. The NMR observation suggests that in solution, these compounds exist as mixtures of neutral species [Co(DH)2(L)(SCN)] and the salt [Co(DH)2(SCN)2]. TG and DT analysis show that these complexes proceed through polymeric intermediate, and give Co3O4 as the end product. |
