title: 1,2-Di-2-pyridylethyl-ene-phenyl-succinic acid (1/1).
abstract: In the title 1:1 adduct, C(10)H(10)O(4)·C(12)H(10)N(2), the two components are linked by O-H⋯N hydrogen bonds to form a one-dimensional chain. The dihedral angle between the pyridine rings is 15.68 (8)° These chains are further inter-connected by weak inter-molecular C-H⋯O hydrogen bonds and weak C-H⋯π inter-actions to generate a three-dimensional network.
