Copper(I) complexes with N-(diisopropoxythiophosphoryl)thiobenzamide PhC(S)NHP(S)(OiPr)2

Solid-state 31 P and 109 Ag 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 ¹⁰⁹ Ag and ³¹ P CPMAS NMR spectroscopy. ¹⁰⁹ 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 ¹⁰⁹ 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 ¹ J(³¹ P-^107/109 Ag) and ² J(³¹ P-³¹ P) values were determined and analyzed.

Synthesis of the first chiral polynuclear copper(i) complex based on (R)-1-(1-phenyl)ethyl-3-(O,O-diethylthiophosphoryl)thiourea and its characterization in the solid state and solution

The reaction of chiral N-thiophosphorylated thiourea with Cu(ii) acetate is accompanied by copper reduction and leads to the formation of a polynuclear complex with the core composed of six Cu(i) ions alternating with sulfur atoms.
