Silver(I) complexes of selenones, [LAgNO3] and [AgL2]NO3 (where L is imidazolidine-2-selenone or diazinane-2-selenone and their derivatives) have been prepared and characterized by elemental analysis, IR and NMR (1H, 13C and 107Ag) spectroscopy. An upfield shift in the C=Se resonance of selenones in 13C NMR and a downfield shift in N-H resonance in 1H NMR are consistent with selenium coordination to silver(I). In 107Ag NMR, the AgNO3signal is deshielded by 450-650 ppm on coordination to selenones. Greater upfield shifts in 13C NMR were observed for [LAgNO3] compared to [AgL2]NO3complexes, whereas the opposite trend was observed for 1H and107Ag NMR chemical shifts.
