title: N,N'-Bis(4-methyl-phen-yl)naphthalene-1,4-dicarboxamide N,N-dimethyl-acetamide disolvate.
abstract: The title compound, C(26)H(22)N(2)O(2)·2C(4)H(9)NO, crystallizes in an anti C=O orientation. The two amide groups are approximately perpendicular to the naphthalene ring system [dihedral angles = 88.89 (1) and 89.08 (1)°]. Each of the dimethyl-acetamide solvent mol-ecules are disordered over two positions, with occupancies of 0.655 (12):0.345 (12) and 0.531 (13):0.469 (13). The crystal packing is stabilized by N-H⋯O and C-H⋯O hydrogen bonds.
