摘要: Twenty-two new coordination compounds are reported with acetaldehyde, propionaldehyde and benzaldehyde as the ligands, viz. M(CH3CHO)6(In-Cl4)2, M(CH3CHO)6(FeCl4)2, M(C2H5CHO)6(InCl4)2 M(C6H5CHO)6(In-Cl4)2 M is Mg, Mn, Fe, Co, Ni (except for acetaldehyde) Zn. In complexes carbonyl stretching vibration shifted to lower frequencies compared this in free ligands. The magnitudes of shifts dependent on metal ions. Frequency-shifts other ligand vibrations also observed. When ions follow Irving-Williams sequence. For acetaldehyde solvates a metal-dependent absorption band appears far infrared, which attributed metal-ligand vibration. This was not observed solvates. Investigation field spectra indicated presence octahedral species M(O)62+ solid compounds. Values Dq B Co(II) Ni(II) reported. A possible relationship between groups attached CO group values obtained spectrochemical parameter described.
