The homoleptic complexes Y (L = PMe3, PMe2Ph, PMePh2, PPh3, PPh2H, PPhH2, AsMe3, AsMe2Ph, AsMePh2, AsPh3, SbMe3, SbEt3 or SbPh3; Y = PF6 or BF4) and Y have been prepared from Y and L or L-L.The 63Cu and, where appropriate 31P-<1H> NMR spectra, have been recorded from CH2Cl2 solutions of the complexes over the temperature range 300-175 K, including the first reported 63Cu resonances from arsenic and antimony donor ligand compounds.The effects of ligand size and geometry upon the 63Cu NMR spectra are discussed and typical copper chemical-shift ranges for Group 15 donor ligand compounds established.The structure of PF6 has been established by X-ray crystallography: orthorhombic, space group P2₁2₁2₁, a = 14.775(6), b = 16.991(5), c = 21.027(6) Angstroem, Z = 4.The copper atom is in a distorted tetrahedral environment .
