Crystal and molecular structure of 1-methyl-4-phenyl-1H-2,3-benzodiazepine
Abstract
The title compound is the product of the cyclisation of an α-(o-alkenylaryl)diazoalkane, and the structure determination establishes the isomer formed in this reaction. All hydrogen atoms were located, and C(1) is shown to be tetrahedrally substituted. The seven-membered heterocyclic ring is biplanar, being bent about a line through C(1) with an interior interplanar angle of 110°. The N–N distance in the ring is 1·255 Å.
