In the mol-ecular structure of the title compound, C(11)H(14)Br(2)N(2)O, the dimethyl-propionamide substituent is twisted slightly with respect to the pyridine ring, the inter-planar angle being 12.3 (2)°. The dibromo-methyl group is orientated in such a way that the two Br atoms are tilted away from the pyridine ring. In the crystal structure, mol-ecules are associated into supra-molecular chains by weak C-H⋯O inter-actions. The crystal is further stabilized by weak N-H⋯Br and C-H⋯N inter-actions.
在标题化合物C(11)H(14)Br(2)N(2)O的分子结构中,二甲基丙酰胺取代基相对于吡啶环略有扭曲,平面间夹角为12.3 (2)°。二溴甲基基团的取向使得两个Br原子远离吡啶环倾斜。在晶体结构中,分子通过弱的C-H⋯O相互作用缔合形成超分子链。晶体通过弱的N-H⋯Br和C-H⋯N相互作用进一步稳定。
