The crystal structure of tribenzylaluminum*diethyl etherate has been determined by single crystal X-ray diffraction techniques.It crystallizes in the monoclinic system, space group P21, with unit cell dimensions of a 8.106(1), b 15.098(2), c 10.037(1) Angstroem, β 111.02(1) degree, V 1146.6(3) Angstroem3, and Z = 2.The final full matrix least-squares refinement on 1139 data gave RF 3.8 and RwF 5.2percent.The compound is similar to other organoaluminum adducts yielding a four coordinate aluminum atom with average Al-C distances of 1.986 and an Al-O distance of 1.901(4) Angstroem which is significantly shorter than the Al-O distance observed in other ether adducts.The average C-Al-C and C-Al-O angles are 113 and 106 degree, respectively.
