摘要：

Double condensation of N-p-nitrophenyl-C-ethoxycarbonylnitrilimine with 2-methyl-4-phenyl-l,5-benzodiazepine leads to two stereoisomers of the title compound, diethyl 3a-methyl-4a-phenyl-3,5-bis(p-nitrophenyl)-3a,4,4a,5- tetrahydro-3//-bis[ 1,2,4]triazolo[4,3-a:3′,4′-d] [ 1,5] benzodiazepine-1,7-dicarboxylate trichloromethane solvate. The stereochemistry of the major derivative was established. The 3a-methyl and the 4a-phenyl groups are trans. The oxadiazoline rings are quite planar while the seven-membered benzodiazepine ring adopts a Cl barrier conformation. © 1995 International Union of Crystallography.
