Air- and moisture stable tungsten(VI) calixarene complex was prepared from [W(eg)(3)] (H(2)eg = 1,2-ethanediol) and H(4)tbcalix (p-tert-butylcalix[4] arene) by a ligand exchange reaction. X-ray structure of [W(tbcalix)(eg)] reveals that tungsten ion is octahedrally surrounded by six oxygen atoms. The reaction of the obtained complex with thionyl chloride or water leads to known dichloro and oxo complexes. (C) 1998 Elsevier Science Ltd. All rights reserved.
