RESUMO
The infrared and Raman spectra of the two hydrates of strontium oxalate, SrC2O4â H2O and SrC2O4â 2H2O, were recorded and discussed on the basis of their structural peculiarities and in comparison with the spectra of the related calcium oxalates and other previously investigated metallic oxalates.

The infrared and Raman spectra of synthetic moolooite, Cu(C2O4).nH2O, were recorded and analyzed on the basis of its structural characteristics and by comparison with related species. The thermogravimetric analysis of the investigated samples show that the water content n, was equal to 0.2. The electronic (reflectance) spectrum of the complex was also recorded and briefly discussed.
