Abstract
- A family of three- and four-coordinated silver(I) complexes of formulas [Ag(PPh <subscript>3</subscript> ) <subscript>2</subscript> L], [Ag(PPh <subscript>3</subscript> )L], and [AgL] <subscript>n</subscript> with N-thiophosphorylated thiourea and thioamide ligands of general formula RC(S)NHP(S)(OPri) <subscript>2</subscript> [R = Ph, PhNH, iPrNH, tBuNH, NH <subscript>2</subscript> ] have been studied by solid-state <superscript>109</superscript> Ag and <superscript>31</superscript> P CPMAS NMR spectroscopy. <superscript>109</superscript> Ag 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 <superscript>109</superscript> Ag chemical shifts and chemical shifts anisotropies. The silver chemical shift ranges for different P,S-environments and coordination state were discussed in detail. The <superscript>1</superscript> J( <superscript>31</superscript> P- <superscript>107/109</superscript> Ag) and <superscript>2</superscript> J( <superscript>31</superscript> P- <superscript>31</superscript> P) values were determined and analyzed.<br /> (© 2022 John Wiley & Sons Ltd.)
