Popis:	New copper(I) and silver(I) halide–trimethylphosphine adducts have been prepared by reaction of MX with PMe3 in benzene suspension, and characterised by room-temperature single-crystal X-ray studies and/or solid state CP MAS 31P NMR and vibrational spectroscopy. The complex [Ag4Cl4(PMe3)3] is a one-dimensional polymer of quasi-cubanoid Ag4Cl4 units disposed with their body diagonals coincident with the crystallographic 3 axis, and linked by Ag–Cl units between the four-co-ordinate apical atoms of successive Ag4Cl4 units, isomorphous with its Cu counterpart. The first solid state NMR study of Cu/Ag PMe3 complexes is reported. The CP MAS 31P NMR and the far-IR and Raman spectra of the complexes [{CuI(PMe3)}4], [CuCl(PMe3)3] and [{AgX(PMe3)2}2] (X = Cl or Br) show the structures to be tetrameric cubane, monomeric pseudo-tetrahedral and dimeric halide-bridged respectively.
