Rare earth(III) complexes with an amido acid derived from isonicotinic acid hydrazide: syntheses, characterization and antifungal activities

Rare earth(III) complexes, RE2(CPI)3xnH2O (RE=La,Ce,Pr,Sm, Gd, Tb, Dy, Er,Yb, Sc, n=3; RE=Nd, Eu, n=4;H2CPI=1-[(N-carboxymethyl-N-phenyl)amino]acetylisonicotinic acid hydrazide), have been synthesized and characterized by IR, UV and (1)H NMR spectroscopy, magnetic susceptibility, elemental analysis, molecular conductivity and TGA measurement. Preliminary pharmacological teste showed that these complexes exhibit definite inhibition activities against S.Sake Yake and C. Albicans (Robin) Berkh 50.
