Mixed-ligand Complexes of Cobalt(II) and Nickel(II) with 1-Hydroxymethyl-5(3)-methylpyrazole-3(5)-carboxylic Acid and Heterocyclic Amines

With 1-hydroxymethyl-5(3)-methylpyrazole-3(5)-carboxylic acid (HmMPzH2) as primary ligand, mixed-ligand complexes of the types, M(HmMPzH)2*2B-nH2O and M(HmMPzH)2*B-B*nH2O have been isolated and characterised in solid state.Magnetic and electronic spectral data classify all the mixed-ligand complexes as normal pseudooctahedral ones.Ir data indicate that the primary ligand (HmMPzH2) behaves as a monoprotic bidentate (N-O) one, through the carboxylic acid function with deprotonation and the pyrazolyl (tertiary) ring nitrogen, whereas the hydroxymethyl group present in 1-position of the pyrazole ring does not take part in complex formation under the experimental conditions.
