(E)-1,5-Di­phenyl­pent-2-en-4-yn-1-one

The title compound, C(17)H(12)O, has an E conformation about the C=C bond. The C—C C—C torsion angle is 7.7 (2)°, and the mean planes of the phenyl­ethyl­enone [r.m.s. deviation = 0.059 (1) Å] and phenyl­acetyl­ene [r.m.s. deviation = 0.023 (1) Å] fragments form a dihedral angle of 14.16 (7)°.

Sumario:The title compound, C(17)H(12)O, has an E conformation about the C=C bond. The C—C C—C torsion angle is 7.7 (2)°, and the mean planes of the phenyl­ethyl­enone [r.m.s. deviation = 0.059 (1) Å] and phenyl­acetyl­ene [r.m.s. deviation = 0.023 (1) Å] fragments form a dihedral angle of 14.16 (7)°. In the crystal, weak C—H⋯O inter­actions link the mol­ecules into zigzag chains propagated in [010].
