The complexes trans-[M(LH)2(H2O)2] (M=Mn, Co, Ni, Cu, Zn; LH(-)=teh monoanion of malonamic acid) have been synthesized and the X-ray crystal structures of the copper(II) and zinc(II) complexes show an octahedral geometry around the metal ion in both molecules. The ligand LH(-) acts as a bidentate chelate with ligated atoms being the amide and one of the carboxylate oxygens. Both structures are stabilized through similar, intermolecular 2D hydrogen bonds. The thermal decomposition data, magnetic susceptibilities, and electronic, variable-temperature ESR and FT-IR spectraof the complexes are discussed in terms of the nature of bonding and kn own structures.
