Mw. Day et al., A DIPHENYLCYCLOPROPENE COMPLEX OF TUNGSTEN, 2O(PMEPH(2))(2)(ETA(2)-3,3-DIPHENYLCYCLOPROPENE)], PRECURSOR TO A TUNGSTEN-OXO-OLEFIN METATHESIS CATALYST, Acta crystallographica. Section C, Crystal structure communications, 52, 1996, pp. 2460-2462
The title compound, P)[(1,2-eta)-3,3-diphenylcyclopropene]oxotungsten,
[WCl2O(C15H12)(C13H13P)(2)], is a mononuclear complex with an approxi
mately octahedral environment around the metal atom. The 3,3-diphenylc
yclopropene ligand is bonded to the W atom in a eta(2)-geometry, with
effectively identical metal-to-carbon bond distances [W-C1 2.133 (7) a
nd W-C2 2.131 (7) Angstrom].
