Crystal structure of (2E,4E)-5-[bis(2-hydroxyethyl)amino]-1-(4-chlorophenyl)-5-phenylpenta-2,4-dien-1-one

Acta Crystallographica Section E: Crystallographic Communications, 2015
In the title compound, C21H22ClNO3, the pentadiene unit is nearly planar [maximum deviation = 0.023 (1) Å], but the carbonyl O atom deviates significantly [by 0.304 (1) Å] from its mean plane, which is twisted with respect to the phenyl and chlorobenzene
