Inorganic Chemistry, 1996Co-Authors: Veronica Garciamontalvo, Raymundo Ceaolivares, Daniel J Williams, Georgina EspinosaperezAbstract:The tetraphenylimidodiphosphinate [N-(P,P-diphenylphosphinoyl)-P,P-diphenylphosphinimidate] ion forms stable tris-chelates with the Bi(III), In(III), and Ga(III) cations. The crystal and molecular structures of [M{(OPPh2)2N}3] (M = Ga, In, Bi) were determined by X-ray diffractometry. The geometry around the Bismuth Atom in compound 3 displays an approximately C3v symmetry. This arrangement suggests the presence of a stereoactive lone pair of electrons, which is located in one of the triangular octahedral faces. Derivative 3 crystallizes in the triclinic space group P1 with Z = 2, a = 14.006(6) A, b = 14.185(4) A, c = 17.609(8) A, α = 88.45(2)°, β = 79.34(2)°, and γ = 78.23(2)°. The structures of the gallium(III) and indium(III) tris-chelate oxygen-based complexes (1 and 2, respectively) were compared with the Bismuth analogue in order to determine the ligand steric bulk influence on the coordination sphere in the absence of the electron lone pair. Complex 1 crystallizes as the [Ga{(OPPh2)2N}3]·CH2Cl2 sol...

Bismuth Atom tailoring of indium oxide surface frustrated lewis pairs boosts heterogeneous co2 photocatalytic hydrogenation
Nature Communications, 2020Co-Authors: Tingjiang Yan, Linlin Wang, Weiguang Ran, Paul N Duchesne, Lili Wan, Nhat Truong Nguyen, Lu Wang, Meikun Xia, Geoffrey A OzinAbstract:The surface frustrated Lewis pairs (SFLPs) on defect-laden metal oxides provide catalytic sites to activate H2 and CO2 molecules and enable efficient gas-phase CO2 photocatalysis. Lattice engineering of metal oxides provides a useful strategy to tailor the reactivity of SFLPs. Herein, a one-step solvothermal synthesis is developed that enables isomorphic replacement of Lewis acidic site In3+ ions in In2O3 by single-site Bi3+ ions, thereby enhancing the propensity to activate CO2 molecules. The so-formed BixIn2-xO3 materials prove to be three orders of magnitude more photoactive for the reverse water gas shift reaction than In2O3 itself, while also exhibiting notable photoactivity towards methanol production. The increased solar absorption efficiency and efficient charge-separation and transfer of BixIn2-xO3 also contribute to the improved photocatalytic performance. These traits exemplify the opportunities that exist for Atom-scale engineering in heterogeneous CO2 photocatalysis, another step towards the vision of the solar CO2 refinery.
