N,N′-Bis(4-methylphenyl)naphthalene-1,4-dicarboxamide N,N-dimethylacetamide disolvate

Abstract

The title compound, C26H22N2O2·2C4H9NO, 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 dimethylacetamide solvent molecules 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.
