Crystal structure of (E)-5,5-dimethyl-2-[3-(4-nitro-phen-yl)allyl-idene]cyclo-hexane-1,3-dione.
In the title compound, C17H17NO4, the cylohexane-1,3-dione ring adopts an envelope conformation with the dimethyl-subsituted C atom as the flap. Its mean plane is inclined to the benzene ring by 7.99 (19)°. The mol-ecule has a trans conformation about the bridging C=C bonds of the ally-idene chain. In the crystal, mol-ecules are linked via pairs of C-H⋯O hydrogen bonds, forming inversion dimers. The dimers are linked by further C-H.·O hydrogen bonds, forming sheets lying parallel to (10-1).
