Abstract
In the title compound, C(18)H(19)F(3)N(2)O(7), the tetrahydropyridine ring adopts a half-chair conformation. The nitro group is disordered over two sites with occupancies of 0.780 (15) and 0.220 (15). An intra-molecular N-H⋯F hydrogen bond is observed in the mol-ecular structure. The mol-ecules are linked into a two-dimensional network parallel to (100) by O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds.
摘要
在标题化合物C₁₈H₁₉F₃N₂O₇中，四氢吡啶环呈半椅式构象。硝基在两个位置上无序分布，占有率分别为0.780 (15) 和0.220 (15)。在分子结构中观察到分子内N-H⋯F氢键。分子通过O-H⋯O、N-H⋯O和C-H⋯O氢键连接成平行于(100) 的二维网络。
