Abstract
Department of Chemistry, Osmania University, Hyderabad-500 007, India E-mail : ssnsirasani @yahoo.com Manuscript received 23 September 2002, revised 23 April 2003. accepted 11 July 2003 A series of cyano (ligand) cobaloximes have been prepared where, the ligand is pyrazole (Pz), 1-(acetamido)pyrazole (Apz), 1-(N-methylacetamido)pyrazole (MAPz), 1-(acetamido)-3,5-dimethylpyrazole (MADMPz). The complex K[(CN)Co(D2H2)SCN] reacts with cthanolic solution of pyrazole or pyrazole amido ligands to form mixed ligand complexes. In all these complexes, the pyrazoles act as monodentate ligands and bind to CoIII through N-2 of pyrazolc ring.
