Crystal structure of (E)-5,5-dimethyl-2-[3-(4-nitro­phen­yl)allyl­idene]cyclo­hexane-1,3-dione

In the title compound, C(17)H(17)NO(4), 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 mol­ecule has a trans conformation about the bridging C=C bonds of the ally­idene c...

Descripción
Sumario:In the title compound, C(17)H(17)NO(4), 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 mol­ecule has a trans conformation about the bridging C=C bonds of the ally­idene chain. In the crystal, mol­ecules 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).
