Crystal structure of N-(7-dibromomethyl-5-methyl-1,8-naphthyridin-2-yl)benzamide–pyrrolidine-2,5-dione (1/1)

Abstract

The title compound, C17H13Br2N3O·C4H5NO2, is a co-crystal of N-(7-dibromomethyl-5-methyl-1,8-naphthyridin-2-yl)benzamide and pyrrolidine-2,5-dione (succinimide). The benzamide molecule exhibits pseudo-mirror symmetry, with an r.m.s. deviation of the non-H atoms of 0.09 Å (except for the two Br atoms). The angle between the least-squares planes of the two molecules is 26.2 (2)°. In the crystal, the two molecules are mutually linked by N—H...O and N—H...N hydrogen bonds. The packing is consolidated by C—H...(O,N) hydrogen bonds and π–π stacking interactions.
