Abstract

Three group 13 dialkylphosphido complexes have been prepared with group 13–15 stoichiometrics of 1:2, [t-Bu(i-Pr₂P)Ga(μ-P-i-Pr₂)]₂ (1) and [i-Pr(i-Pr₂P)In(μ-P-i-Pr₂)]₂ (2), and 2:3, [t-Bu(i-Pr₂P)Ga(μ-P-i-Pr₂)₂Ga(Cl)t-Bu] (3). These complexes were prepared in moderate yields via the reaction of the appropriate lithium dialkylphosphide and alkyl group 13 halide in the desired stoichiometric ratio. Each compound has been characterized by elemental analysis, ¹H and ³¹P NMR, and mass spectroscopy. The structures of 2 and 3 were established by X-ray crystallography. Crystal data for 2: space group P2₁/c, a = 11.283(1) Å, b = 11.429(5) Å, c = 15.836(3) Å, β = 104.19(1)°, V = 1980(6) Å³, Z = 4, R = 0.0401. Crystal data for 3: space group P2₁/c, a = 18.453(4) Å, b = 9.516(2) Å, c = 20.745(4) Å, β = 106.88(3)°, V = 3486(2) Å³, Z = 8, R = 0.0551. Both compounds feature structures with four-membered M₂P₂ rings.
