ABSTRACT
The title compound, C17H13Br2N3O·C4H5NO2, is a co-crystal of N-(7-di-bromo-methyl-5-methyl-1,8-naphthyridin-2-yl)benzamide and pyrrolidine-2,5-dione (succinimide). The benzamide mol-ecule exhibits pseudo-mirror symmetry, with an r.m.s. deviation of the non-H atoms of 0.09â Å (except for the two Br atoms). The angle between the least-squares planes of the two mol-ecules is 26.2â (2)°. In the crystal, the two mol-ecules are mutually linked by N-Hâ¯O and N-Hâ¯N hydrogen bonds. The packing is consolidated by C-Hâ¯(O,N) hydrogen bonds and π-π stacking inter-actions.
ABSTRACT
The mol-ecule of the title 1,8-naphthyridine-BF2 derivative, C12H10BBr2F2N3O, is located on a mirror plane running parallel to the entire ring system and the attached methyl C atoms. Individual mol-ecules are stacked along the b-axis direction. The cohesion in the crystal structure is accomplished by C-Hâ¯F hydrogen bonds and additional off-set π-π inter-actions [centroid-to-centroid distance = 3.6392â (9)â Å, slippage 0.472â Å], leading to the formation of a three-dimensional supra-molecular network.
