  Adducts of GaI3 and InI3 with Ph3P and Ph3As

  摘要：

  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.

  Indium(III) iodide forms both 1:1 and 1:2 adducts with triphenylphosphine, depending on the reaction conditions, and especially on the solvent used. The complex InI_3•PPh₃ involves four-coordination at indium; the structure is trigonal, with a = 15.105(4) Å, c = 16.769(7) Å, V = 3313(2) ų, Z = 6, and space group [Formula: see text]. Crystals were also obtained in which InI_3•PPh₃ and InI₃(PPh₃)₂ are present in a 1:1 ratio; these are also trigonal, a = 15.473(4) Å, c = 41.701(7) Å, V = 8646.1(1.8) ų,Z = 3 + 3 and space group [Formula: see text]. The 1:2 adduct has approximately D_3h symmetry in the InI₃P₂ kernel. The bond distances and angles are discussed; in particular, the In—P bonds are extremely weak in the 1:2 adduct. This compound has been shown by ³¹P NMR to undergo complete dissociation in solution to InI_3•PPh₃ and PPh₃. The addition of R₄NI (R = n-C₃H₇, n-C₄H₉) causes quantitative conversion to InI₄⁻ and free Ph₃P. Similar experiments are reported for the compound InI₃(dppe) (dppe = 1,2-bis(diphenylphosphino)ethane), whose structure is an infinite chain of InI₃ units linked through In-P-C₂H₄-P-In coordination. The crystal structure showed that InI₃(dppe) cocrystallizes with an equimolar quantity of dppe; these crystals are cubic, a = 41.445(14) Å, b = 15.944(8) Å, c = 16.533(11) Å, p = 102.02(4)°, V = 10 685(9) ų, Z = 4 + 4, space group C₂/c, Solid state and solution phase results are discussed in terms of the coordination chemistry of indium(III).
