5)-cyclopentadienyl](l-a-oxidobenzylidene-1:2j 2 O:C)titanium(IV)tungsten(0)

By Catharine Esterhuysen, I. B. Jacques Nel, Matthias W and Stephanie Cronje


R factor = 0.025; wR factor = 0.062; data-to-parameter ratio = 15.2. The title compound, [TiW(C 5H 5) 2(C 7H 5O)Cl(CO) 5], consists of two metal centres, with a (tungstenpentacarbonyl)oxyphenylcarbene unit coordinated by a titanocene chloride. The oxycarbene group is nearly planar, with the phenyl ring twisted by an angle of 39.1 (2) with respect to this plane. One of the cyclopentadienyl rings undergoes an offset face-to-face – interaction [3.544 (6) A ˚ ] with the symmetry-related cyclopentadienyl ring of a neighbouring molecule.
