Crystal structure of ethyl 8-chloro-4-oxo-1,4-di-hydro-quinoline-3-carboxyl-ate.

Yoshinobu Ishikawa1, Nanako Yoshida1.   

Abstract

In the title compound, C12H10ClNO3, the asymmetric unit comprises two independent mol-ecules, and the dihedral angle between the least-square planes of the quinoline ring systems of these mol-ecules is 73.30 (5)°. In the crystal, N-H⋯O hydrogen bonds between the independent mol-ecules lead to supra-molecular layers parallel to (-1-10); both N-H H atoms are bifurcated.

Refinement. Refinement was performed using all reflections. The weighted R-factor (wR) and goodness of fit (S) are based on F2. R-factor (gt) are based on F. The threshold expression of F2 > 2.0 σ(F2) is used only for calculating R-factor (gt).
