Infrared and Raman spectra of N2H5HC2O4 and N2D5DC2O4 have been recorded at various temperatures between 77 and 300 K. The results at 300 K are consistent with the known crystal structures of these solids. A phase transition has been detected at ∼ 240 K in N2D5DC2O4 and although there are similarities between the two stable solid phases of this compound, the low-temperature form appears to be centrosymmetric and to have a larger unit cell than the high-temperature modification.
