摘要：

Ag-I complexes of thiourea (tu) having the general formula Ag(tu)(x)NO3 (x=1-4) have been prepared and characterized by elemental analyses, i.r. and n.m.r. (H-1, C-13, N-15 and Ag-107) spectroscopy. Separate i.r. bands were observed for terminal and bridging tu ligands in the complexes. The Ag(tu)NO3 complex is assumed to be polymeric with all tu groups in the bridging mode. A consistent upfield shift in the C-13-n.m.r. chemical shift is observed as the number of tu groups attached to Ag-I increases, whereas the opposite trend is observed for H-1, N-15 and Ag-107 chemical shifts.
