1-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)°].

The ten-membered fused ring of the title compound, C(12)H(10)N(2)O, is essentially planar in the two independent mol-ecules of the asymmetric unit (r.m.s. deviations = 0.012 and 0.015 Å).

The title compound, C(8)H(8)N(2)S, was prepared by the condensation of N-methyl-1,2-phenyl-enediamine and carbon disulfide. The crystal structure is stabilized by a C-H⋯π inter-action between a benzene H atom and the benzene ring of a neighbouring mol-ecule, and by inter-molecular N-H⋯S inter-actions.

In the title compound, C20H18N2P, the P atom is bonded to the two phenyl and imidazole groups, with an average P-C bond length of 1.828 (2) Å. The three C-P-C bond angles have values consistent with a tetra-hedral geometry around the P atom with the fourth site occupied by a H atom. Crystal packing is through van der Waals inter-actions.
متن کامل4-Methyl-1-phenylquinolin-2(1H)-one
In the title compound, C(16)H(13)NO, the mol-ecules are connected three-dimensionally through non-classical C-H⋯O and C-H⋯π inter-actions of 3.272 (3), 3.380 (3) and 3.382 (4) Å. Classical hydrogen bonds are not observed. The dihedral angle between the benzyl and quinolin-2(1H)-one mean planes is 87.15 (7)°
