In the title compound, C(26)H(24)Br(2)N(2)O(2), the central naphthalene system carries two Br atoms and two -CH(2)CH(2)NHC(6)H(5) substituents. The phenyl rings of the latter residues are inclined at 74.17 (17) and 51.4 (2)° with respect to the naphthalene ring system. Each alkyl chain adopts a fully extended all-cis conformation with respect to the naphthalene and phenyl rings [N-C-C-O torsion angles = 68.6 (4) and 60.5 (4)°]. In the crystal, one of the N-H groups forms bifurcated N-H⋯(Br,O) hydrogen bonds, which link the mol-ecules into inversion-related dimers. The centrosymmetric dimers are aggregated via pairs of C-H⋯π inter-actions into sheets parallel to (110).
