Crystal structure of 3,4′-diphenyl-3′-p-tolyl-4′H-spiro[indan-2,5′-[1,2]oxazol]-1-one
In the title compound, C30H23NO2, the five-membered rings are both in envelope conformations with the same spiro C atom as the flap. The benzene ring and the two phenyl rings are inclined to the mean plane of the indene ring system by 83.98 (8), 81.46 (8) and 72.31 (7)°. In the crystal, mol-ecules are linked by pairs of C-H⋯O hydrogen bonds into inversion dimers. The dimers are further connecte...

In the racemic title compound, C20H15NO2S, the planes of the two phenyl substituents form dihedral angles of 48.97 (15) and 69.26 (15)° with that of the fused benzene ring of the parent benzo-thia-zine ring, while the heterocyclic thia-zine ring exhibits a screw-boat pucker. The O atom on the S atom of the ring is pseudo-axial on the thia-zine ring and trans to the 2-phenyl group. In the crysta...

In the title compound, C16H15NO2S [alternative name: rac-2,3-diphenyl-1,3-thia-zinan-4-one 1-oxide], the thia-zine ring exhibits an envelope conformation, with the S atom forming the flap. The sulfoxide O atom is in a pseudo-axial position on the thia-zine ring and is trans to the phenyl group on C-2. The phenyl rings form a dihedral angle of 89.47 (19)°. In this racemate crystal, homochiral mo...
متن کاملCrystal structure of (Z)-1-(3,4-dichlorophenyl)-3-methyl-4-[(naphthalen-1-ylamino)(p-tolyl)methylidene]-1H-pyrazol-5(4H)-one
The title Schiff base compound, C28H21Cl2N3O, was synthesized by the condensation of 1-(3,4-di-chloro-phen-yl)-3-methyl-4-(4-methyl-benzo-yl)-1H-pyrazol-5(4H)-one with 1-aminona-phthalene. The p-tolyl ring is normal to the pyrazole ring, with a dihedral angle of 88.02 (14)°, and inclined to the naphthalene ring system by 78.60 (12)°. The pyrazole ring is inclined to the naphthalene ring system ...

In the cation of the title compound, C(22)H(19)N(2) (+)·NO(3) (-), the N atom in the 3-position of the imidazole is protonated. The three pendant aromatic rings are twisted from the plane of the imadazolium ring by dihedral angles of 38.1 (1), 43.74 (9) and 20.4 (1)°. In the crystal structure, N-H⋯O and N-H⋯(O,O) hydrogen bonds link the mol-ecules to form an infinite one-dimensional chain paral...
