Abstract

The molecular structure of [(tBu)2Al(μ-OC6H5-2-Me)]2 has been determined. Both the ortho-tolyl methyl groups are oriented towards Al(2). The intramolecular steric interaction between the ortho-methyl groups and the tert-butyl ligands results in the geometry about the bridging oxygen being significantly distorted while the geometries about the aluminum centers show a distortion from tetrahedral that is less than the sterically less hindered [(tBu)2Al(μ-OPh)]2. Crystal data: group C2/c, a = 13.733(3) Å, b = 15.135(3) Å, c = 15.420(3) Å, β = 104.24(3)∘, V = 3106(1) Å3, Z = 4, R = 0. 0612, wR2 = 0.1787.
