Infrared Spectra of Metal Chelate Compounds. VI. A Normal Coordinate Treatment of Oxalato Metal Complexes

The infrared spectra of 10 oxalato complexes have been obtained in the frequency range 4000 to 300 cm—1. A normal coordinate treatment made on the 1:1, metal:ligand model of the chelate ring of tris-(oxalato)-Cr(III) resulted in the assignment of metal-oxygen stretching bands in the range between 60...

Description
Summary:The infrared spectra of 10 oxalato complexes have been obtained in the frequency range 4000 to 300 cm—1. A normal coordinate treatment made on the 1:1, metal:ligand model of the chelate ring of tris-(oxalato)-Cr(III) resulted in the assignment of metal-oxygen stretching bands in the range between 600 and 300 cm—1 for various oxalato complexes. The force constants and the band assignments obtained are compared with those of the previous normal coordinate analysis based on the free oxalato ion. Relationships between the metal-oxygen and the carbon-oxygen stretching frequencies are discussed.
