摘要：

Silver(I) complexes of thiones (L), [LAgNO3] and [AgL2]NO3 have been prepared and characterized by elemental analysis, IR and NMR (H-1, C-13, N-15 and Ag-107) spectroscopy. An upfield shift in the C=S resonance of thiones in C-13 NMR and downfield shifts in N-H resonances in H-1 and N-15 NMR are consistent with the sulfur coordination to silver(1). In Ag-107 NMR, the AgNO3 signal is deshielded by 300-500 ppm on its coordination to thiones. Greater upfield shifts in C-13 NMR are observed for [LAgNO3] compared with [AgL2]NO3 complexes, whereas the opposite trend is observed for H-1, N-15 and Ag-107 chemical shifts.
