| Abstract: | The crystal and molecular structure of 1,4-bis(p-chlorobenzoyl)-5-methylene-7-methyl-2,3,4,5-tetrahydro-1H-1,4-diazepine has been determined by X-ray methods. The crystals are triclinic,P¯1,a = 10.605,b = 13.054,c = 7.351 Å,  = 94.24,  = 101.53,  = 101.55 °,Z = 2. The structure was solved by direct methods, and refined by full-matrix least squares toR = 5.6% on 3495  observed reflections. The structure is of the enamide form with diacylation on nitrogen. There are no abnormal bond lengths or intermolecular contacts. |
