Abstract

Cadmium(II) complexes of Imidazolidine-2-selenone (ImSe) and its derivatives have been prepared with the general formula Cd(RImSe) ₂Cl₂ (where R = Me, Et, Pr, etc.). These complexes are characterized by elemental analysis, IR and NMR (¹H, ¹³C, ⁷⁷Se and ¹¹³Cd) spectroscopy. An upfield shift in C=Se resonance of selenones in ¹³C NMR and in ⁷⁷Se and high-frequency shifts in N-H resonances in ¹H are consistent with the selenium coordination to Cd(II). The ⁷⁷Se nucleus in Cd(ImSe) ₂Cl₂ is shielded by 38 ppm on coordination, relative to the free ligand. The principal components of the ⁷⁷Se, ¹¹³Cd and ¹³C shielding tensors for the complexes were determined from solid-state NMR data. Large selenium chemical shift anisotropies were observed for these complexes.
