Solid-state 31P and 109Ag CP/MAS NMR as a powerful tool for studying of silver(I) complexes with N-thiophosphorylated thiourea and thioamide ligands

A family of three- and four-coordinated silver(I) complexes of formulas [Ag(PPh3)(2)L], [Ag(PPh3)L], and [AgL](n) with N-thiophosphorylated thiourea and thioamide ligands of general formula RC(S)NHP(S)(OPri)(2) [R = Ph, PhNH, iPrNH, tBuNH, NH2] have been studied by solid-state Ag-109 and P-31 CPMAS NMR spectroscopy. Ag-109 NMR spectra have provided valuable structural information about Ag coordination, which is in good accordance with the available crystal structure data. The data presented in this work represent a significant addition to the available Ag-109 chemical shifts and chemical shifts anisotropies. The silver chemical shift ranges for different P,S-environments and coordination state were discussed in detail. The (1)J(P-31-Ag-107/109) and (2)J(P-31-P-31) values were determined and analyzed.
