In the title compound,C23H32N4Se, was synthesized and itscrystal structure was determined by single crystal X-ray diffraction. Thecompound crystallizes in orthorhombic system, space group Pbca,a = 10.9960(10)Å, b = 14.9460(9)Å, c =27.565(5)Å and Z = 2. According to X-ray crystallographicstudies, the diazepine ring is observed to be in a disordered state. Thesite-occupancy of the major compenent refined to 0.53(1). The C=Se bondlength of 1.862(4)Å is a double bond character. The dihedral anglebetween the two phenyl rings is 37.7(2)°.
