RESUMO
In the title compounds C23H21ClN2O3 [I, namely 1-(4-chloro-phen-yl)-4-(4-methyl-phen-yl)-3,8-dioxo-1,2,5,6,7,8-hexa-hydro-quine-3-carb-oxy-lic acid] and C24H22N2O3 [II, namely 4-(4-meth-oxy-phen-yl)-1-(4-methyl-phen-yl)-2,5-dioxo-1,2,5,6,7,8-hexa-hydro-quinoline-3-carbo-nitrile], each of the cyclo-hexene and di-hydro-pyridine rings of the 1,2,5,6,7,8-hexa-hydro-quinoline moieties adopts a twisted-boat conformation. The asymmetric units of both compounds I and II consist of two independent mol-ecules (A and B). In II A, three carbon atoms of the cyclo-hexene ring are disordered over two sets of sites in a 0.670â (11):0.330â (11) occupancy ratio. In the crystal of I, mol-ecules are linked through classical N-Hâ¯O hydrogen bonds, forming inversion dimers with an R 2 2(8) ring motif and with their mol-ecular planes parallel to the crystallographic (020) plane. Non-classical C-Hâ¯O hydrogen-bonding inter-actions connect the dimers, resulting in a three-dimensional network. In the crystal of II, mol-ecules are linked by C-Hâ¯N, C-Hâ¯O and C-Hâ¯π inter-actions, forming a three-dimensional network.
RESUMO
The title compound, C21H21NO5, crystallizes with two mol-ecules in the asymmetric unit. In each mol-ecule, the central 1,4-di-hydro-pyridine ring adopts a shallow sofa conformations (with the C atom bearing the phenol ring as the flap), whereas the pendant cyclo-hexene rings both have twisted-boat conformations. Each mol-ecule features an intra-molecular O-Hâ¯O hydrogen bond, which closes an S(8) ring. In the crystal, the mol-ecules are linked by O-Hâ¯O, C-Hâ¯O and C-Hâ¯π inter-actions, forming a three-dimensional network.
