Abstract The Raman spectra of cadmium bromide solutions with bromide to cadmium mole ratios varying from 1.0 to 9.74 were studied at 200°C. Factor analysis revealed that three complexes contributed to the spectra. From a comparison with previous results at 25°C these species were identified as CdBr2, CdBr 3 − , and CdBr 4 2− cadmium existed as the tetrabromo complex, CdBr 4 2− , at mole ratios greater than 5.99. A formation constant of 7±2 was determined for CdBr 4 2− at 200°C. No evidence of Cd(H2O) 6 2+ or CdBr+ was found, although electroneutrality dictates that one or both of these species must exist at low mole ratios.
