The FT infrared spectra of the binuclear copper(II) complex with imidazole and saccharin and of its iminodeuterated analogue at room (RT) and liquid nitrogen temperature (LNT) are recorded. The bands that are mainly due to the NH, ND, CO, SO2 and metal-ligand stretchings are assigned. The spectral characteristics are correlated with the available structural data and compared with the corresponding data for other saccharinates and imidazole complexes. While the spectral appearance in the NH, ND and SO2 regions is in agreement with the structural data, the carbonyl stretchings do not conform the pronounced difference between the lengths of the two structurally non-equivalent carbonyl groups found by earlier structural studies.
