Department of Chemistry, Osmania University, Hyderabad-500 007, India E-mail: ssnsirasani@yahoo.com Manuscript received 6 May 2003, revised 10 February 2004, accepted 11 May 2004 Alkyl(aquo)cobaloximes, [RCo(DH)2(H2O)](R = CH3 and C2H5) have been prepared. These aquo complexes upon reacting with pyridine and substituted pyridincs give alkyl(ligand)cobaloximes [RCo(DH)2L], where L = pyridine, 4-methylpyridine, 4-ethylpyridine and 4-aminopyridine. These cobaloximes are characterized by electronic, IR, 1H NMR and 13C NMR spectral data
