  • synthesis and characterization of the phosphorus Halide Boron Halide complexes x3pby3 x cl br i y br i by 31p mas nmr ir and raman spectroscopy and the crystal structure of br3pbbr3
    European Journal of Inorganic Chemistry, 2000
    Co-Authors: Christoph Aubauer, Gunter Engelhardt, Thomas M Klapotke, Heinrich Noth, Axel Schulz, Marcus Warchhold

    Abstract:

    The phosphorus HalideBoron Halide complexes X3PBY3 (X = Cl, Br, I; Y = Br, I) were prepared and characterized by Raman and IR spectroscopy. Density functional theory (B3LYP) was applied to calculate structural and vibrational data. Assignments of the vibrational normal modes for these Lewis acid−base adducts were made on the basis of their Raman and IR spectra in comparison with computational results. The compounds Cl3PBBr3, Br3PBBr3, I3PBBr3, and I3PBI3 were also studied by solid-state 31P MAS NMR spectroscopy. Second-order 31P−79,81Br dipolar coupling effects were observed in the 31P MAS NMR spectrum of Br3PBBr3. The molecular structure of Br3PBBr3 was determined by X-ray diffraction.

  • on the bonding structure and thermodynamics of phosphorus Halide Boron Halide complexes x 3 p by 3 x y cl br i
    Journal of Molecular Structure-theochem, 2001
    Co-Authors: Ch Aubauer, Thomas M Klapotke, A Schulz

    Abstract:

    Abstract Donor–acceptor complexes X 3 P·BY 3 (X, Y=Cl, Br, I) and their fragments have been studied using density functional (B3LYP) and ab initio methods (MP2, CCSD(T)) with effective core potentials. The bonding, charge transfer and structure of all X 3 P·BY 3 is discussed on the basis of natural bond orbital (NBO) analysis. The estimated free molecular enthalpies of dissociation indicate that all X 3 P·BY 3 represent thermodynamically labile species which are stabilized by the lattice energies in the solid state. The total distortion energy increases in accordance with the decreasing complex dissociation enthalpy. With regard to halogen exchange between the PX 3 and BY 3 moiety in X 3 P·BY 3 (g) adducts, only the complexes where Y=X and where X represents a heavier halogen than Y are thermodynamically stable.
