A series of N-heterocyclic carbene (NHC) Ag(I) complexes have been prepared and used to study the dynamics of NHC ligand exchange in these Ag(I) complexes. These studies used solution-state variable-temperature (VT) 13C NMR spectroscopy and the temperature-dependent changes in 13C- 107/109Ag coupling to determine activation energies for the ligand exchange process. The effects of concentration, bridging anions, and additives on the exchange process have been studied. The experimental activation energies for the NHC ligand exchange processes of these silver complexes are also compared with DFT calculations. The results are consistent with an associative mechanism for the Ag(I)-NHC exchange process.

3:1 adducts of triphenylphosphine, PPh3, with silver halides, AgX, have been characterized for chloride, bromide and iodide by single-crystal X-ray structure determinations, the chloride as its diacetone solvate.Crystals of the chloride, *2(CH3)2CO, are triclinic, P, a 13.654(4), b 14.059(4), c 13.970(4) Angstroem, α 84.82(2), β 87.71(2), γ 75.68(2) deg, Z 2; the structure was refined to a residual R of 0.061 for No = 2428 independent 'observed' reflections.Crystals of the bromide, , are trigonal, P3, a 19.366(6), c 10.787(6) Angstroem, Z 3, R was 0.054 for No = 2362.Crystals of the iodide, , are monoclinic, P21/n, a 18.993(8), b 13.807(4), c 17.78(8) Angstroem, β 96.11(4)deg, Z 4; R was 0.042 for No = 3691.Ag-Cl, Br, I respectively are 2.533(4), 2.671(6)-2.691(4) and 2.858((1) Angstroem, Ag-P for each of the three structures respectively lie in the ranges 2.558(5)-2.582(4), 2.528(3)-2.549(7) and 2.544(2)-2.780(3) Angstroem.
