The title compound, C23H26N2O4, consists of a partially hydrogenated a
cridine moiety with one 2-nitrophenyl substituent on the central ring.
The acridine nucleus suffers considerable deviations from planarity.
The central ring is in a distorted boat conformation, while the two ou
ter rings adopt almost ideal envelope conformations. The phenyl ring o
f the 2-nitrophenyl substituent is perpendicular to the acridine ring
system. Molecules are held together by C-H ... O hydrogen bonds.
