Full Papers


CdII, ZnII, CoII, NiII, CuII and AgI salts of 4-methylpyrazole have been synthesized and compared with those of 3(5)-methylpyrazole and 3,5-dimethylpyrazole. The compounds were characterized and identified by vibrational spectra, ligand-field spectra and chemical analyses. The pyrazolate ion acts as a bidentate ligand in all cases. Tetrahedral and square-planar coordinations have been observed. Tentative assignments of the vibrational spectra of salts and neutral ligand have been made.
