Abstract
The molecular structures of the zinc and cadmium compounds, (Cbp)2ZnBr2 and (Cbp)2CdBr2, which feature a zwitterionic ligand derived from N-(4-carboxybenzyl)pyridinium, have been determined by using X-ray diffraction. Comparison of the structures of (Cbp)2ZnBr2 and (Cbp)2CdBr2 demonstrates that whereas the zinc compound adopts unidentate coordination of the carboxylate ligand, the cadmium counterpart exhibits anisobidentate coordination. The Zn–Br [2.4339(8) Å] and Cd–Br [2.6357(6) Å] bond lengths differ by 0.20 Å, which is in accord with the difference in covalent radii of zinc and cadmium (0.22 Å); as such, it suggests that the previous structure of “(Cbp)2ZnBr2”, which possesses a Zn–Br bond length of 2.635(2) Å, actually corresponds to that of (Cbp)2CdBr2.
