1-[(2-Methyl-8-quinolyl)aminomethylene]naphthalen-2(1H)-one
The mol-ecule of the title compound, C(21)H(16)N(2)O, exists in the keto form and the C=O and N-H bonds are mutually cis in the crystal structure, although an enol form would be possible through tautomerism. The dihedral angle between the quinoline and the naphthalene systems is 22.04 (2)°. A bifurcated intramolecular N-H⋯(O,N) hydrogen bond is present.

Mol-ecules of the title spiro-[4.5]decane derivative, C(17)H(30)N(2)O(3)S, are linked by paired O-H⋯N hydrogen bonds into centrosymmetric R(2) (2)(16) dimers and these dimers are linked into a three-dimensional framework structure by C-H⋯O interactions.
متن کامل(E)-2-(Furan-2-ylmethylidene)-8-methyl-2,3,4,9-tetrahydro-1H-carbazol-1-one
In the title mol-ecule, C(18)H(15)NO(2), the carbazole unit is not planar [maximum deviation from mean plane = 0.236 (2) Å]. The pyrrole ring makes dihedral angles of 1.21 (10) and 16.74 (12)° with the benzene and the furan rings, respectively. The cyclo-hexene ring adopts a half-chair conformation. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R(2) (2)(10) l...
متن کامل1-Methyl-3-phenylquinoxalin-2(1H)-one
The phenyl substituents in both independent mol-ecules of the title compound, C(15)H(12)N(2)O, are twisted with respect to the quinoxaline system [dihedral angles = 19.3 (1) and 30.4 (1)°].
متن کامل1-Methyl-1,3-diazinan-2-one
In the crystal structure of the title compound, C(5)H(10)N(2)O, mol-ecules are connected via pairs of strong N-H⋯O hydrogen bonds into centrosymmetric dimers, which are stacked along the a axis. The molecule is not planar, the dihedral angle between the N/C/N and C/C/C planes being 42.1(1)°.
