Crystal structure of ethyl 8-chloro-4-oxo-1,4-dihydroquinoline-3-carboxylate

Abstract

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

“…All hydrogen atoms were placed in geometrically calculated positions and included in the refinement using riding model. The details of data collection and crystal structure refinement for which we used SAINT Plus, 61 SADABS 62 and SHELXL-2018/3 63 program packages, are summarized in Table S1. † The crystallographic data for Ty7-Cl 2 has been deposited with the Cambridge Crystallographic Data Center, CCDC 2308227 † (https://www.ccdc.cam.ac.uk).…”
