title: 3,5-Dimethyl-1H-pyrazole-2-hy-droxy-5-(phenyl-diazen-yl)benzoic acid (1/1).
abstract: There are two independent 3,5-dimethyl-pyrazole and two independent 2-hy-droxy-5-(phenyl-diazen-yl)benzoic acid mol-ecules [in which intra-molecular O-H⋯O bonds form S(6) graph-set motifs] in the asymmetric unit of the title compound, C(5)H(8)N(2)·C(13)H(10)N(2)O(3). In the crystal, the components are linked by inter-molecular O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds, forming four-component clusters. Further stabilization is provided by weak C-H⋯π inter-actions.
