Abstract

Reaction of AlCl3 with {Me2SiO}n (Dow-Coming high-vacuum grease) at an Al:Si ratio of 1:1 in hexane at room temperature yielded a large crop of colorless crystals of [{ClSiMe 2OAlCl2}2], which were characterized by single-crystal X-ray diffraction and NMR. These crystals hydrolyzed on an aluminum surface to give a coating of silicone oil interspersed with particles of [Al(OH2)6]Cl3, as determined by powder X-ray diffraction and X-ray photoelectron spectrometry.
