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

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.

Ethyl 8-meth-oxy-4-oxo-1,4-di-hydro-quinoline-3-carboxyl-ate.

Project description:In the title compound, C13H13NO4, the asymmetric unit contains four independent mol-ecules, each exhibiting an intra-molecular N-H?O hydrogen bond. The ethyl group in one of the four mol-ecules is disordered, with a refined occupancy ratio of 0.295?(16):0.705?(16). A face-to-face stacking inter-action is found between the benzene rings of the quinoline units of two of the mol-ecules [centroid-centroid distance = 3.541?(2)?Å], which are sandwiched by the other two mol-ecules through N-H?O hydrogen bonding. In the crystal, the sandwiched mol-ecules are assembled via stacking inter-actions along the b-axis direction with their translation-symmetry equivalents [centroid-centroid distance = 3.529?(2)?Å], and are further linked through N-H?O hydrogen bonding. The other two mol-ecules are linked via stacking inter-actions with their inversion-symmetry equivalents [centroid-centroid distances = 3.512?(3) and 3.716?(4)?Å] and via N-H?O hydrogen bonding.

Project description:In the structure of the title compound, C(13)H(14)N(2)O(3)·H(2)O, all atoms of the organic molecule except the terminal methyl group of the ethyl group attached to the N atom of the pyridinone ring are roughly coplanar, with an r.m.s. deviation of 0.0897?Å.
