title: 4-Meth-oxy-3-(4-nitro-benz-yloxy)benzaldehyde.
abstract: In the title compound, C(15)H(13)NO(5), the two benzene rings make a dihedral angle of 3.98 (7)°. The crystal packing is stabilized by weak non-classical inter-molecular C-H⋯O inter-actions that link mol-ecules into centrosymmetric tetra-mers.
