چکیده
In the title compound, 2C(8)H(7)N(3)·C(8)H(6)O(4)·2H(2)O, the pyridine and pyrazole rings are approximately coplanar, the dihedral angle between them being 4.69 (9)°. The asymmetric unit consists of half of the terephthalic acid (an inversion centre generates the other half of the mol-ecule), one 4-(1H-pyrazol-3-yl)pyridine (4pp) mol-ecule and one water mol-ecule. In the crystal, two 4pp and one terephthalic acid mol-ecules form a linear three-molecule unit as a result of O-H⋯N hydrogen bonds. These units are further assembled into a three-dimensional network by two types of hydrogen bonds, viz. O-H⋯O and N-H⋯O.
