  been prepared and their structural and spectroscopic properties compared with those of the phosphinoyl complexes. The results, and competitive solution NMR studies, show that Ga(III) binds the hard R3PO in preference to the softer phosphine or arsine ligands. Hydrolysis of gallium(III) phosphines is shown to lead to [R3PH][GaX4], but in contrast to some other p-block halides, GaX3 do not promote air-oxidation

  Several 1:1 adducts of gallium trihalides with triarylphosphines, X3Ga(PR3) (X=Cl, Br, and I; PR3=triarylphosphine ligand), were investigated by using solid‐state 69/71Ga and 31P NMR spectroscopy at different magnetic‐field strengths. The 69/71Ga nuclear quadrupolar coupling parameters, as well as the gallium and phosphorus magnetic shielding tensors, were determined. The magnitude of the 71Ga quadrupolar

  The solid state structures of the compounds GaI₃•PPh₃ and Ga₂I₆•dppe ( dppe = 1,2-bis(diphenylphosphino)ethane ) have been determined. For the former, in which the GaI₃P core has C_3v symmetry, the structure is trigonal, with a = 14.961(2) Å, c = 16.509(3) Å, V = 3199.5(4) ų, Z = 6, space group [Formula: see text]. In Ga₂I₆•dppe, the ligand bridges two GaI₃P centres; the structure is monoclinic, a = 10.196(7) Å, b = 15.363(1) Å, c = 23.027(9) Å, β = 98.735(4)°, V = 3565.1(3.2) ųZ = 4, space group P2_1/n The use of ³¹P NMR spectroscopy shows that GaI₃•PPh₃ is slightly dissociated in nonaqueous solution, and the effect of adding Ph₃P or I⁻ has been investigated. Similar studies with Ga₂I₆•dppe are also reported. In each system, four-coordination at gallium is dominant; an equally important factor is the dimerization of uncomplexed GaI₃ to Ga₂I₆ in these solutions. Keywords: gallium(III) iodide, complexes, phosphorus, NMR, crystallography.

  Adducts Ph3PGaI3 and Ph3AsGaI3 obtained by adding the ligands to Et2OGaI3 have been investigated by Ga-71 NMR, IR/Raman spectroscopy and X-ray diffraction. Et2OInI3 with Ph3P gives (Ph3P)(3)(InI3)(2). Ph3As yields (Ph3As)(3)(InI3)(2) . H2O as rhombohedral crystals whose structure was solved by X-ray diffraction. Both these indium complexes contain Ph3EInI3 molecules alongside five-coordinate adducts (Ph3E)(2)InI3 with the Ph3E ligands attached in axial sites by long and unequal bonds to a planar InI3 unit. Vibrational assignments are made for Ph3PGaI3, Ph3AsGaI3, Ph3EInI3 and (Ph3E)(2)InI3 (E = P or As). (C) 1997 Elsevier Science S.A.
