Vibrational spectra of the α-MIIC2O4.2H2O oxalato complexes, with MII = Co, Ni, Zn

Abstract

The infrared and Raman spectra of the α-MIIC2O4⋅2H2O oxalate complexes with MII = Co, Ni and Zn were recorded and briefly discussed on the basis of their structural peculiarities. The IR spectrum of a partially deuterated sample of α-ZnC2O4⋅2H2O is also discussed, reinforcing some of the performed assignments in the lower energy spectral region.

Se registraron los espectros de infrarrojo y Raman de los oxalato-complejos α-MIIC2O4⋅2H2O con MII = Co, Ni, Zn y se los discute brevemente en base a sus peculiaridades estructurales. Asimismo, se discute el espectro IR de una muestra parcialmente deuterada de α-ZnC2O4⋅2H2O el que permitió reforzar algunas de las asignaciones realizadas en la zona espectral de baja energía.
