(E)-2-{2-tert-Butyl-6-[2-(4-hy­droxy­phen­yl)ethen­yl]-1-propyl-1,4-dihydro­pyridin-4-yl­idene}indane-1,3-dione

The title compound, C(29)H(29)NO(3), the nearly planar nine-membered indanedione ring [maximum deviation = 0.027 (2) Å] is located approximately parallel to its carrier pyridine ring [maximum deviation = 0.021 (2) Å] with a dihedral angle of 1.8 (1)° between the planes. However, because of steric hindrance, the benzene ring [maximum deviation = 0.006 (2) Å] is not parallel to the pyridine ring [dihedral angle = 37.29 (8)°]. The mol­ecules display numerous inter­molecular π–π inter­actions between the five- and six-membered rings, the shortest centroid–centroid distance being 3.796 (2) Å. There are inter- and intra­molecular O—H⋯O and C—H⋯O hydrogen bonds.
