5-Amino-1-phenyl-1H-pyrazole-4-carboxylic acid

In the mol­ecule of the title compound, C(10)H(9)N(3)O(2), the pyrazole ring is approximately coplanar with the amino and carboxyl groups. The phenyl group is twisted by 48.13 (3)° relative to this plane. An intra­molecular N—H⋯O hydrogen bond stabilizes the planar conformation of the mol­ecule. The...

description In the mol­ecule of the title compound, C(10)H(9)N(3)O(2), the pyrazole ring is approximately coplanar with the amino and carboxyl groups. The phenyl group is twisted by 48.13 (3)° relative to this plane. An intra­molecular N—H⋯O hydrogen bond stabilizes the planar conformation of the mol­ecule. The mol­ecules are linked into two-dimensional sheets by two strong inter­molecular N—H⋯N and O—H⋯O hydrogen bonds. The latter forms the classic carboxylic acid dimer motif.
