title: 7-Meth-oxy-1-(4-nitro-benzo-yl)naph-thalen-2-yl 4-nitro-benzoate.
abstract: In the title compound, C(25)H(16)N(2)O(8), the dihedral angle between the naphthalene ring system and the benzene ring of the nitro-phenyl ketone unit is 82.64 (7)°. The bridging ester O-C(=O)-C plane makes dihedral angles of 42.12 (8) and 11.47 (9)°, respectively, with the naphthalene ring system and the benzene ring of the nitro-phenyl ester unit. In the crystal, two types of weak inter-molecular C-H⋯O inter-actions are observed.
