2-Amino-3,4,5,6-tetra­fluoro­benzoic acid

The asymmetric unit of the title compound, C(7)H(3)F(4)NO(2), obtained as an inter­mediate in the synthesis of a coupling reagent, contains four independent and conformationally similar mol­ecules. The amine H atoms form both intra­molecular and inter­molecular N—H⋯O(carbox­yl) hydrogen bonds which,...

description The asymmetric unit of the title compound, C(7)H(3)F(4)NO(2), obtained as an inter­mediate in the synthesis of a coupling reagent, contains four independent and conformationally similar mol­ecules. The amine H atoms form both intra­molecular and inter­molecular N—H⋯O(carbox­yl) hydrogen bonds which, together with inter­molecular O—H⋯O(carbox­yl) hydrogen bonds and N—H⋯F associations form ribbon structures along the a axis.
