“…3 where one major resonance is observed at 32.5 ± 0.1 ppm; this 31 P shift for PPh 3 is located further downfield and deshielded in comparison to other transition metal PPh 3 adducts involving Cu and Ag. 19,20 This observation is also in agreement with corresponding 31 P solution NMR measurements where a similar shift at 31.19 ppm is observed for complex 4 in CDCl 3 solution.…”

“…2 the connectivity between these P sites is established through the presence of this homonuclear 2 J( 31 P, 31 P) interaction, which shows the two resonances clearly resolved and correlated above and below the main diagonal. The observation of 2 J( 31 P, 31 P) from inequivalent P positions in solid bisand tris-Ag-phosphine and Cu-phosphine complexes has been previously well established [11][12][13][14][15]. The large chemical shift separation between the chemical shifts d 1 and d 2 , and the marked difference in the 1 J( 31 P, 107/109 Ag) measurements corroborates the very different bonding strengths exhibited by these PPh 3 moieties.…”

“…The application of this technique has been discussed in detail elsewhere. 30 The recycle delay, contact period, 1 H π/2 pulse width and MAS rate were the same as those implemented in the above 1D 31 P CPMAS experiments. A total of 256 F1 increments were acquired into 256 word blocks, with both dimensions zero-filled to 1 K words and weighted with Gaussian multiplication prior to Fourier transformation.…”
