3,3'-{Ethane-1,2-diylbis[carbonylbis(azanediyl)]}dipyridinium tetra-chloridoplatinate(II).

In the crystal structure of the title compound, (C(14)H(18)N(6)O(2))·[PtCl(4)], the cation and square-planar anion are located on special positions (on a twofold axis and an inversion centre, respectively). In the crystal structure, N-H⋯Cl hydrogen bonds lead to a staircase-like motif. The central ethane backbone of the cation is disordered over two positions of equal occupancy.
