Synthesis and structural studies of a 1:2 adduct of silver(I) tetrakis(pyrazolyl)borate(III) with a tertiary phosphine

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

“…The overall 1 J ( 31 P– 107,109 Ag) values are observed in the most of our samples (the only exception is the complex 4 , see later) and also in the previous studies. [ 18,19 ]…”

“…T A B L E 1 31 P isotropic chemical shifts and 1 J P-Ag and 2 J P-P coupling constants of Ag complexes Compound δ iso , ppm (±0.1 ppm) values are observed in the most of our samples (the only exception is the complex 4, see later) and also in the previous studies. [18,19] The 1 H-31 P CPMAS spectra of 2, 3, and 5 show singlet signals for the thiophosphoryl group and two doublet of doublets for the inequivalent PPh 3 phosphorus atoms, which are a result of 1 J( 31 P-107/109 Ag) and 2 J( 31 P-31 P) coupling (Figure S1). The NMR measurements fit with the X-ray studies of the mononuclear complex 2, containing three different P sites.…”
