In the crystal structure of the title compound, (C14H18N6O2)·[PtCl4], 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
