Crystal structure of (2E,4E)-5-[bis-(2-hy-droxy-eth-yl)amino]-1-(4-chloro-phen-yl)-5-phenyl-penta-2,4-dien-1-one.

In the title compound, C21H22ClNO3, the penta­diene unit is nearly planar [maximum deviation = 0.023 (1) A], but the carbonyl O atom deviates significantly [by 0.304 (1) A] from its mean plane, which is twisted with respect to the phenyl and chloro­benzene rings by 71.34 (13) and 46.40 (13)°, respectively. In the crystal, inversion-related molecules are linked by two pairs of O—H⋯O hydrogen bonds, forming chains propagating along [01-1], enclosing R22(16) and R22(22) ring motifs. The chains are linked via C—H⋯O hydrogen bonds and C—H⋯π inter­actions into a three-dimensional supra­molecular architecture.
