Lewis-base adducts of group 11 metal(I) compounds. LXV: Synthesis, spectroscopy and structural systematics of some 1 : 3 adducts of copper(I) compounds with triphenylarsine, [(Ph3As)3CuX], X = Cl, Br, I, ONO2

Crystallization of some copper(I) salts, CuX, with triphenylarsine in 1 : 3 stoichiometry from acetonitrile has yielded an array of adducts, [(Ph3As)3CuX], characterized by room-temperature single crystal X-ray structure determinations. [(Ph3As)3CuCl] (1) has been characterized in two unsolvated phases, α and β, the second form previously recorded as monoclinic, P21/n, Z = 8. The 'α' phase, like the bromide (2) and iodide (3), adopts the trigonal P 3 array, widespread among many [(Ph3E)3MX] adducts with a ≈ 19, c ≈ 11 A?; conventional R on |F| was 0.037, 0.041, 0.056 for No 3458, 3259, 3434 independent 'observed' (I > 3σ(I)) reflections for these three adducts respectively. A further form, γ, is a toluene hemisolvate, monoclinic, P21/c, a 21.490(5), b 10.218(7), c 24.901(6) A?, β 117.53(2)°, Z = 4, R 0.057 for No 7207. The nitrate (4), obtained as a monosolvate from methanol, is monoclinic, P21/n, a 15.115(9), b 23.201(9), c 14.170(14) A?, β 92.56(7)°, Z = 4, R 0.049 for No 5476. In all compounds, the copper atom is four-coordinate, E3CuX, the nitrate in (4) being -ONO2 unidentate. The CuX bond lengths r(CuX) in [(Ph3E)3CuX] (X = Cl, Br, I) show a decrease from the Ph3P to the corresponding Ph3As compound, and this is consistent with the observed increase in the v(CuX) wavenumbers in the far-infrared spectra. These trends are both consistent with an increase in the CuX bond strength from the Ph3P to the Ph3As complexes, and possible reasons for this are discussed.
