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.
