Two oxotungsten(VI) complexes of the type [WOCl2(OAr)(2)] (OAr = OC6H3-Bu-2-Me-6 or OC6H2-'Bu-2-Br-4-Me-6) were prepared by the reaction of WOCl4 with 2 equiv. of phenolic ligand precursors in a refluxing toluene solution. Both compounds form monomeric units, in which the tungsten ion has adopted a square pyramidal coordination geometry with the oxo ligand in the apical position and phenoxide groups bound in a trans orientation.
