摘要：

Following our earlier reports on copper(I) mixed-ligand complexes with heterocyclic thiones and triphenylphosphine, we now report the isolation of 12 new complexes of the general formula [Cu(PPh3)2(L)X] [L = 1-methyl-1,3-imidazoline-2-thione (meimtH), 5-methyl-2-benz-1,3-imidazoline-2-thione (mebzimtH2), purine-6-thione (pur6SH), quinoline-2-thione (qn2SH) and X = Cl, Br, I], and their characterization by various physico-chemical methods. The crystal structure of the complex [Cu(PPh3)2(meimtH)Br] is also reported. Crystals are prisms, space group P1 with a = 9.988(3), b = 10.212(2), c = 21.066(5) Å, α = 94.86(2), β = 91.70(2), γ = 119.16(2)° and Z = 2. The metal ion has a distorted tetrahedral geometry with bond lengths CuS = 2.375(1), CuBr = 2.509(0), CuP(1) = 2.268(1) and CuP(2) = 2.281(1) Å. The structure has been solved by single-crystal X-ray diffraction methods with a final R of 0.0330 for observed reflections with Fo ≥ 6.0β(Fo). © 1990.
