Synthesis and Crystal Structure of 1,3,3a,5-Tetraphenyl-3a,4,5,11-tetrahydro-3H,6H-1,2,4-triazolobenzodiazepine

Abstract

Abstract: The title compound was synthesized by [2+3] cycloaddition reaction of 2,4-diphenyl-2,3-dihydro-1H-1,5-benzodiazepine and benzenecarbohydrazonic chloride and its crystal structure was determined by Xray diffraction method. The single crystals belong to orthorhombic, space group Fdd2 with a=1.7628(4) nm, b=5.7512(12) nm, c=1.0227(2) nm, V=10.368(5) nm³, Z=16, D_C= 1.262 g·cm^-3, μ=0.075 mm^-1, F(000)=4160 for 1339 reflections, R=0.0461, R_W= 0.0560.

Key words: 3a,4,5,11-Tetrahydro-3H,6H-1,2,4-triazolo[4,3-d][1,5]benzodiazepine, Crystal structure, Molecular structure
