Abstract
In the title compound, C(11)H(10)N(3)O(4)S(+)·C(2)F(3)O(2) (-), the benzene ring makes an angle of 87.3 (2)° with the pyridinium ring. The nitro group is essentially coplanar with the benzene ring. The F atoms of the CF(3) group are disordered over two positions with almost equal occupancy [0.531 (12)/0.469 (12)]. The crystal structure is stabilized by N-H⋯O and C-H⋯O hydrogen bonds.
摘要
在标题化合物C(11)H(10)N(3)O(4)S(+)·C(2)F(3)O(2) (-)中，苯环与吡啶鎓环形成87.3 (2)°的夹角。硝基基本上与苯环共面。CF(3)基团的F原子在两个位置上无序分布，占有率几乎相等[0.531 (12)/0.469 (12)]。晶体结构通过N-H⋯O和C-H⋯O氢键得以稳定。
