N,N'-Bis(4-chloro-phen-yl)naphthalene-1,4-dicarboxamide N,N-dimethyl-formamide disolvate.

In the title compound, C(24)H(16)Cl(2)N(2)O(2)·2C(3)H(7)NO, the two C=O groups adopt an anti orientation. The two amide groups are twisted away from the naphthalene ring system by 59.10 (4) and 68.22 (4)°. The crystal packing is stabilized by N-H⋯O and C-H⋯O hydrogen bonds.
