The title compound 7-chloro-5-cyclopropyl-9-methyl-10-(4-nitro-benzyl)-5,10-dihydro-4,5,6,10-tetraaza-dibenzo [a,d] cyclohepten-11-one was synthesized and characterized spectroscopically and finally confirmed by X-ray diffraction study. The title compound crystallizes in the monoclinic space group P21/c with cell parameters a=11.644(8) , b=14.826(1) , c=15.919(8) , =90, =130.377(4),=90, V=2093.5(2) 3, and Z=4. The NO2 group in the ring is almost in the same plane of the nitrobenzyl ring. The structure exhibits neither inter nor intra molecular hydrogen bonding.
