R factor = 0.042; wR factor = 0.133; data-to-parameter ratio = 10.8. The title compound, C45H27P, was obtained as a product of the reaction of triphenylmethylenephosphorane with one molar equivalent of 1,4-diphenylbutadiyne in toluene. The compound was very stable under ambient conditions, but rapidly decomposed in solution when exposed to the air. The P atom is tetracoordinated in an approximately tetrahedral geometry. The length of the C C triple bond [1.206 (2) A ˚]is in the normal range. Related literature Related crystal structures of,-unsaturated-C,P ylides have been reported, see: Koollenz et al. (1996).
