The title compound crystallizes in the monoclinic space group A 2/m (C2h3) with a = 10.61(3) Å, b = 9.511(5) Å and c = 16.47(5) Å, β = 124.2(1)° and two formula units in the unit cell. The structure was solved by Patterson and Fourier methods and refined by least squares to R = 0.071 based on 1251 observed intensities. The organic cations are slightly distorted and are arranged in dimers along the crystallographic a-axis. There are "mixed stacks" of the planar [Pt(CN)4]2− units which are
