title: 4,4'-[Oxalylbis(azanediyl)]dipyridinium bis(perchlorate).
abstract: In the title molecular salt, C(12)H(12)N(4)O(2) (2+)·2ClO(4) (-), the complete cation is generated by crystallographic inversion symmetry. In the crystal, the cations and anions are linked via N-H⋯O and N-H⋯(O,O) hydrogen bonds, forming a three-dimensional framework.
