Reaction of TeCl4 with Al(CH3)3 in toluene affords the crystalline product .The title compounds crystallized in the monoclinic space group P2₁/n with unit cell parameters a = 11.630(3), b = 12.595(4), c = 8.409(2) Angstroem, β = 89.97(2) deg, and D_c = 1.62 g cm^-3 for Z = 4.Least-squares refinement based on 1354 observed reflections I >/= 3?(I) in the range 3.5 < 2Θ < 45.0 deg led to a final R factor of 0.046 (R_w = 0.067).The compound does not exist as discrete cations and anions but may be desribed as an organotelluronium-aluminum oligomer.The mean Te-C bond distance is 2.130(11) Angstroem while the mean Al-Cl bond distance is 2.221(4) Angstroem.
