Methyl 1-ethyl-7-methyl-4-oxo-1,4-di-hydro-1,8-naphthyridine-3-carboxyl-ate monohydrate.

ABSTRACT: 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. In the crystal, C-H?O contacts link pairs of naphthyridine mol-ecules into head-to-tail dimers. These are joined by strong O-H?O hydrogen bonds from the water molecules into infinite chains along the a axis.

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.

Ethyl 7-oxo-3,5-diphenyl-1,4-diazepane-2-carboxyl-ate.

Project description:The title compound, C(20)H(22)N(2)O(3), crystallizes with two independent mol-ecules in the asymmetric unit. In both mol-ecules, the diazepane rings adopt chair conformations. The mean planes of the diazepane rings in the two molecules form dihedral angles of 71.6?(4)/40.3?(5) and 75.9?(5)/58.6?(7)° with the neighbouring benzene rings. The carbonyl-group O atoms deviate significantly from the diazepane rings, by 0.685?(14) and 0.498?(13)?Å. The eth-oxy-carbonyl groups show conformational difference between two mol-ecules, as reflected in the orientation of the carbonyl O atoms and the C-C-O-C torsion angle of -179.0?(2)° in one mol-ecule and 73.2?(2)° in the other. In one molecule there is a short N-H?O contact that generates an S(5) ring motif. In the crystal, N-H?O inter-actions generate R(2) (2)(8) graph-set motifs and C-H?O inter-actions generate R(2) (2)(10) and R(2) (2)(14) graph-set motifs. C-H?? inter-actions also occur.
