Crystal structure of 3-(4-hydroxyphenyl)-2-[(E)-2-phenylethenyl]quinazolin-4(3H)-one
The title compound, C22H16N2O2 {systematic name: 3-(4-hy-droxy-phen-yl)-2-[(E)-2-phenyl-ethen-yl]quinazolin-4(3H)-one}, consists of a substituted 2-[(E)-2-aryl-ethen-yl]-3-aryl-quinazolin-4(3H)-one skeleton. The substituents at the ethyl-ene fragment are located in trans positions. The phenyl ring is inclined to the quinazolone ring by 26.44 (19)°, while the 4-hy-droxy-phenyl ring is inclined t...

Mol-ecules of the title compound, C11H9NOS3, are built up by one thio-phene and one 2-thioxa-thia-zolidin-4-one ring which are connected by a methyl-ene bridge. In addition, there is an allyl substituent attached to nitro-gen. The two rings are almost coplanar, making a dihedral angle between them of 0.76 (11)°. The allyl group is oriented perpendicular to the mean plane through both ring syste...
متن کاملCrystal structure of 3-amino-2-propylquinazolin-4(3H)-one
In the title mol-ecule, C11H13N3O, the propyl group is almost perpendicular to the quinazolin-4(3H)-one mean plane, making a dihedral angle of 88.98 (9)°. In the crystal, mol-ecules related by an inversion centre are paired via π-π overlap, indicated by the short distances of 3.616 (5) and 3.619 (5) Å between the centroids of the aromatic rings of neighbouring mol-ecules. Inter-molecular N-H⋯N ...
متن کاملCrystal structure of (E)-4-hydroxy-6-methyl-3-{1-[2-(4-nitrophenyl)hydrazinylidene]ethyl}-2H-pyran-2-one
The title compound, C14H13N3O5 (HMNP), was synthesized by the simple condensation of p-nitro-phenyl-hydrazine with de-hydro-acetic acid (DHA) in a 1:1 molar ratio in ethanol. HMNP has been characterized by using FT-IR, 1H and 13C NMR and UV-Vis spectroscopic and single-crystal X-ray diffraction techniques. The crystal packing reveals strong hydrogen bonds between the NH group and the carbonyl O...
متن کاملCrystal structure of 5-(4-methylphenyl)-3-[(E)-2-(4-methylphenyl)ethenyl]cyclohex-2-en-1-one
In the title compound, C22H22O, the dihedral angle between the planes of the benzene rings is 53.55 (7)°. Weak C-H⋯O inter-actions help to direct the packing, forming sheets lying parallel to (020).
