3-[2-(Triphenyl­phosphanyl­idene)acet­yl]-2H-chromen-2-one

In the title compound, C(29)H(21)O(3)P, a coumarin-substitued ylid, the P atom is linked to three benzene rings and a planar coumarin moiety via a methyl­enecarbonyl group. The bond lengths in the P=C–C=O fragment clearly indicate a delocalized system involving the olefinic and carbonyl bonds. The m...

Sumario:In the title compound, C(29)H(21)O(3)P, a coumarin-substitued ylid, the P atom is linked to three benzene rings and a planar coumarin moiety via a methyl­enecarbonyl group. The bond lengths in the P=C–C=O fragment clearly indicate a delocalized system involving the olefinic and carbonyl bonds. The mol­ecular structure is stabilized by an intra­molecular C—H⋯O inter­action that results in an S7 graph-set ring motif. In the crystal, mol­ecules are linked into a three-dimensional framework by C—H⋯O hydrogen bonds.
