Crystal structure of (E)-5,5-dimethyl-2-[3-(4-nitro-phen-yl)allyl-idene]cyclo-hexane-1,3-dione.

ABSTRACT: 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).

(E)-2,2-Dimethyl-5-(3-phenyl-allyl-idene)-1,3-dioxane-4,6-dione.

Project description:The title compound, C(15)H(14)O(4), was prepared by the reaction of 2,2-dimethyl-1,3-dioxane-4,6-dione and (Z)-3-phenyl-acryl-aldehyde in ethanol.

2-[2-(4-Nitro-phen-yl)hydrazinyl-idene]-1,3-diphenyl-propane-1,3-dione.

Project description:In the mol-ecular structure of the title compound, C(21)H(15)N(3)O(4), the inter-planar angle between the benzoyl units is 89.7?(1)°. The corresponding angles between the phenyl-hydrazono and the benzoyl groups are 31.4?(3) and 60.8?(2)°, respectively. In the crystal, a strong resonance-assisted intra-molecular hydrogen bond (N-H?O) and a weak intra-molecular hydrogen bond (C-H?N) strongly affect the observed conformation of the mol-ecule. The crystal packing is determined by a strong inter-molecular hydrogen bond (N-H?O), giving rise to a helical chain along the a axis. In addition, two weak inter-molecular contacts (C-H?O) are observed.

4-[(Dimethyl-amino)methyl-idene]-2-(4-nitro-phen-yl)-1,3-oxazol-5(4H)-one.

Project description:The title mol-ecule, C(12)H(11)N(3)O(4), is essentially planar, the r.m.s. deviation for all non-H atoms being 0.068?Å. An intra-molecular C-H?N hydrogen bond occurs. The crystal packing is dominated by ?-? inter-actions [shortest centroid-centroid distance = 3.6312?(16)?Å], which lead to supra-molecular chains that are linked into a three-dimensional network via C-H?O contacts. The crystal was found to be a non-merohedral twin (twin law -1 0 0/0 -1 0/ 0.784 0 1), the fractional contribution of the minor component being approx-imately 22%.
