ResumoComprehensive Raman and infrared spectroscopic studies of copper (II) oxalate dihydrate and dipotassium bis-oxalato copper (II) tetrahydrate in the solid state and the Raman spectrum of dipotassium bis-oxalato copper (II) in aqueous solution are reported. Comparisons are made with the vibrational spectra of potassium oxalate and with previous infrared data for the bis-oxalato compound. Copper (II) oxalate dihydrate contains coordinated oxalate and is spectroscopically similar to the nickel (II) analogue, which has an extended polymer chain structure. The bis- oxalato copper (II) compound consists of discrete Cu(C2,O4)2-2 ions which have a square planar, centrosymmetric structure with D2h molecular symmetry.
