Abstract

We present a systematic study of the complexation of the new pseudopeptidic ligand isophthaloylbisglycine (H₂IBG) with divalent metal ions of varying ionic radius. This work represents the initial employment of H₂IBG in the coordination chemistry of alkaline earth, 3d transition, Zn(II) and Cd(II) metal elements. Infrared, NMR, thermal, magnetic, adsorption and theoretical studies of these compounds are also discussed.
