Addition of the primary phosphine tBuPH2 or the primary arsine tBuAsH2 to tBu3M (M = Ga, Al) followed by heating or photolysis affords the complexes tBu2M(μ-E(tBu)H)>n (1; M = Ga, E = P; n = 2; 2, M = Al, E = P, n = 2; 3, M = Ga, E = As, n = 3; 4, M = Al, E = As, n = 3).For each compound, the degree of association was assessed on the basis of 1H, 31P, 13C NMR and mass spectroscopy.The anti-isomer of 1 (1a) was also characterized by X-ray crystallography.Crystal data for 1a; C24H56Ga2P2, monoclinic, space group C2/m, a 17.124(7), b 11.755(7), c 8.700(3) Angstroem, V 1561.94(15) Angstroem3, Z = 4, Dcalc 1.157 g cm-3, μ(MoKα) 18.3 cm-1.A total of 1501 unique reflections was measured over the range 3.0 2θ 50.0 deg (θ-2θ scan mode) and 1263 of these with I above 3?(I) were used in the refinement to afford final R and Rw values of 0.059 and 0.070, respectively.
