VIBRATIONAL SPECTRA OF THE α-M II C 2 O 4 ⋅2H 2 O OXALATO COMPLEXES, WITH M II = Co, Ni, Zn

The infrared and Raman spectra of the α-M II C2O4⋅2H2O oxalate complexes with M II = 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.
