Crystal structure of 1′-(2-methylpropyl)-2,3-dihydrospiro[1-benzothiopyran-4,4′-imidazolidine]-2′,5′-dione
In the title compound, C15H18N2O2S, the 2,3-di-hydro-1-benzo-thio-pyran ring adopts a sofa conformation and the hydantoin ring is twisted with respect to the benzene ring at 78.73 (17)°. In the crystal, pairs of N-H⋯O hydrogen bonds link the mol-ecules into inversion dimers.
متن کاملCrystal structure of 1-(piperidin-1-yl)butane-1,3-dione
In the title compound, C9H15NO2, the piperidine ring exhibits a chair conformation. The butane-dione subunit exhibits a conformation with the ketone C atom in an eclipsed position with respect to the amide carbonyl group. In the crystal, a two-dimensional layered arrangement is formed by hydrogen bonds of the C-H⋯O type between the methyl group and the exocyclic methyl-ene unit as donor sites a...

In the title compound, C13H14N2O2, the C5 ring has an envelope conformation with the C atom adjacent to the quaternary C being the flap. The five atoms comprising the imidazolidine-2,4-dione ring are almost planar (r.m.s. deviation = 0.004 Å). The dihedral angle between the five-membered rings is 89.66 (10)°. In the crystal, inversion-related mol-ecules are connected via {⋯HNCO}2 synthons. Thes...
متن کاملCrystal structure of (E)-1-(2-nitrobenzylidene)-2,2-diphenylhydrazine
The title compound, C19H15N3O2, shows an E conformation of the imine bond. The dihedral angle between the planes of the phenyl rings in the di-phenyl-hydrazine groups is 88.52 (4)°. The 2-nitro-benzene ring shows a torsion angle of 10.17 (8)° with the C=N-N plane. A short intra-molecular C-H⋯O contact occurs. In the crystal, only van der Waals contacts occur between the mol-ecules.
