1,3-Dimethyl-3-tetradecyl-1H-1,5-benzodiazepine-2,4(3H,5H)-dione
The seven-membered ring of the title compound, C25H40N2O2, adopts a boat-shaped conformation (with the C atoms of the fused-ring as the stern and the methine C atom as the prow). The tetradecyl substituent occupies an equatorial position, with the tetradodecyl chain exhibibiting an an all-trans conformation
1,5-Dimethyl-3-propargyl-1H-1,5-benzodiazepine-2,4(3H,5H)-dione
The asymmetric unit of the title compound, C14H14N2O2, comprises two independent molecules, which slightly differ in the orientation of the propargyl chain. In both molecules, the diazepine ring adopts a boat conformation with the propargyl-bearing C atom as the prow and the C atoms at the ring junction as the stern. The carbonyl O atom of one independent molecule is hydrogen bonded to the acetylenic H atom of the other independent molecule. In the crystal, symmetry-related molecules are linked together by C—H⋯O hydrogen bonds, forming a ribbon-like structure along the c axis
7-Chloro-1,5-dipropargyl-1H-1,5-benzodiazepine-2,4(3H,5H)-dione
The seven-membered ring of the title compound, C15H11ClN2O2, adopts a boat-shaped conformation (with the C atoms of the fused-ring as the stern and the methylene C atom as the prow). The N atoms exists in a trigonal–planar coordination; one of the acetylenic H atoms forms a C—H⋯O hydrogen bond to the O atom of an adjacent molecule, generating a linear chain along a body diagonal
