title: 2-Meth-oxy-1-(2-meth-oxy-4-nitro-naphthalen-1-yl)-6-nitro-naphthalene.
abstract: In the title compound, C22H16N2O6, the naphthalene ring systems form a dihedral angle of 65.2 (1)°. Two O atoms of one of the nitro groups are disordered over two sets of sites with occupancy factors of 0.586 (15) and 0.414 (15). Weak C-H⋯O inter-molecular inter-actions are present, forming a ladder like structure along the a axis.
