research communications (GO)Synthesis and crystal structure of allyl 7-(diethylamino)-2-oxo-2H-chromene-3-carboxylate
The crystal structure of the title compound, C17H19NO4, consists of nearly planar molecules that are linked by intermolecular C—H⋯O hydrogen bonding into chains along the b-axis direction.
research communications (GO)Crystal structures of 1-(4-chlorophenyl)-4-(4-methylphenyl)-2,5-dioxo-1,2,5,6,7,8-hexahydroquinoline-3-carboxylic acid and 4-(4-methoxyphenyl)-1-(4-methylphenyl)-2,5-dioxo-1,2,5,6,7,8-hexahydroquinoline-3-carbonitrile
The asymmetric units of compounds I and II both consist of two independent molecules. In the crystal of I, molecules are linked through N—H⋯O hydrogen bonds, forming inversion dimers with ![[R_{2}^{2}]](./)
(8) ring motifs and with their molecular planes parallel to (020). C—H⋯O interactions connect the dimers, forming a three-dimensional network. In the crystal of II, molecules are linked by C—H⋯N, C—H⋯O and C—H⋯π interactions, resulting in a three-dimensional network.
