Ethyl 6-chloro-2-oxo-4-phenyl-1,2-dihydro-quinoline-3-carboxyl-ate.

In the title compound, C(18)H(14)ClNO(3), the dihydro-quinolin-2-one ring system is almost planar (r.m.s. deviation = 0.033 Å). The carboxyl-ate plane and the phenyl group are twisted away from the dihydro-quinolin-2-one ring system by 50.3 (1) and 64.9 (1)°, respectively. In the crystal structure, inversion-related mol-ecules form R(2) (2)(8) dimers via pairs of N-H⋯O hydrogen bonds.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
