1,8-Bis(4-amino­benzo­yl)-2,7-dimeth­oxy­naphthalene

The title compound {systematic name: [8-(4-aminobenzoyl)-2,7-dimethoxynaphthalen-1-yl](4-aminophenyl)methanone}, C(26)H(22)O(4)N(2), possesses crystallographically imposed twofold symmetry, with two C atoms lying on the rotation axis. In the crystal, the mol­ecules inter­act through inter­molecular N—H⋯O hydrogen bonds between the amino and meth­oxy groups on the naphthalene ring systems and N—H⋯π inter­actions between the amino groups and the naphthalene rings. Furthermore, weak C—H⋯O hydrogen bonds and π–π stacking inter­actions between the benzene rings are observed. The centroid–centroid and inter­planar distances between the benzene rings of the aroyl group and the naphthalene ring systems of adjacent mol­ecules are 3.6954 (8) and 3.2375 (5) Å, respectively. The dihedral angle between the mean planes of the benzene ring and the naphthalene ring system is 83.59 (5)°. The benzene ring and the carbonyl group in the benzoyl unit are almost coplanar [C—C—C—O torsion angle = 175.91 (10)°].
