Vibrational analysis of some transition metal complexes with deprotonated and neutral malonamide
Malonamide forms neutral complexes MX2(LH2)2 with first row transition metals (M Mn, Fe, Co, Ni, Cu, Zn; X Cl, Br, I, NCS, ONO2; LH2 H2NCOCH2CONH2). CuX2(LH2)1 (X Cl, Br) could also be isolated. In alkaline medium, malonamide forms anionic complexes (ML2)2−.xH2O (M Ni, Cu). A complete vibrational analysis (infrared and Raman spectroscopy) has been worked out and the metal—ligand vibrations clearly prove the weak field in the octahedral MX2(LH2)2 complexes. Spectroscopic evidence for the Jahn—Teller effect in the Cu complex is given by the metal—ligand vibrations, the hydrogen bonding and the Raman intensities of the ν(CO) and ν(CN).
