title: Di-2-pyridyl disulfide-succinic acid (1/1).
abstract: In the title compound, C(10)H(8)N(2)S(2)·C(4)H(6)O(2), both components of the cocrystal lie on crystallographic twofold rotation axes. In the di-2-pyridyl disulfide mol-ecule, the dihedral angle between the two pyridine rings is 66.6 (1)°. In the crystal structure, inter-molecular O-H⋯N and weak C-H⋯O hydrogen bonds link both types of mol-ecules into columns along the c axis.
