5-Amino-1-phenyl-3-trifluoromethyl-1H-pyrazole-4-carboxylic acid
In the title compound, C(11)H(8)F(3)N(3)O(2), there are two molecules in the asymmetric unit wherein the phenyl rings make dihedral angles of 65.3 (2) and 85.6 (2)° with the pyrazole rings. In the crystal, pairs of molecules are held together by O—H⋯O hydrogen bonds between the carboxyl groups, fo...

| Sumario: | In the title compound, C(11)H(8)F(3)N(3)O(2), there are two molecules in the asymmetric unit wherein the phenyl rings make dihedral angles of 65.3 (2) and 85.6 (2)° with the pyrazole rings. In the crystal, pairs of molecules are held together by O—H⋯O hydrogen bonds between the carboxyl groups, forming a centrosymmetric dimer with an R (2) (2)(8) motif. Intramolecular N—H⋯O interactions are also present. |
