W.-T. Bi, N.-L. Hu and J.-H. Bi

Abstract: The title compound, C₁₄H₁₆N₈O₂²⁺·2ClO₄^-, was prepared by reaction of bis[amino(2-pyridyl)methylene]oxalohydrazide with perchloric acid. The molecular symmetry is C_i and thus the asymmetric unit comprises one half-molecule. The dihedral angle between the aromatic ring and the plane of the oxamide group is 70.8 (3)°. The perchlorate anions and the cations are connected by intermolecular N-HO hydrogen bonds.
