Crystal structure of (E)-5,5-dimethyl-2-[3-(4-nitrophenyl)allylidene]cyclohexane-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...
متن کاملCrystal structure of 2-(diphenylphosphanyl)phenyl 4-(hydroxymethyl)benzoate
The title compound, C26H21O3P, was obtained as by-product due to the hydrolysis of the desired tosyl-ated compound. The dihedral angles between the three aromatic rings attached to the P atom lie in the range 78.1 (1)-87.6 (1)°. The hy-droxy-methyl group is disordered between two conformations in a 0.719 (9):0.281 (9) ratio. The hy-droxy H atom is not involved in inter-molecular inter-actions, ...
متن کامل2-[(3,5-Dimethyl-1-phenyl-1H-pyrazol-4-yl)methylidene]indan-1,3-dione
In the title compound, C(21)H(16)N(2)O(2), the five-membered heterocyclic ring makes a dihedral angle of 47.06 (6)° with the attached benzene ring, whereas the indan-1,3-dione ring system and the benzene ring are oriented at a dihedral angle of 21.92 (7)°. In the crystal, inversion dimers linked by pairs of C-H⋯O hydrogen bonds generate R(2) (2)(22) loops. Aromatic π-π stacking inter-actions [c...
متن کاملCrystal structure of 4-[(E)-(4-hydroxybenzylidene)amino]-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one
The asymmetric unit of the title compound, C18H17N3O2, comprises three independent mol-ecules (1, 2 and 3). In mol-ecule 1, the dihedral angles between the pyrazolone ring and the pendant phenyl and hydroxybenzene rings are 54.43 (6) and 28.72 (6)°, respectively. The corresponding data for mol-ecule 2 are 86.84 (6) and 25.69 (5)°, respectively, and for mol-ecule 3 are 47.41 (7) and 17.09 (7)°, ...
متن کاملCrystal structure of 5-[4-(diethylamino)benzylidene]-2,2-dimethyl-1,3-dioxane-4,6-dione
The title compound, C17H21NO4, consists of substituted Meldrum's acid with a [4-(di-ethyl-amino)-phen-yl]methyl-idene fragment attached to the fifth position. The heterocycle assumes a distorted boat conformation. The planar part of heterocycle is almost coplanar with the benzene ring due to the presence of a long conjugated system in the mol-ecule. This leads to the formation of C-H⋯O-type int...
