Abstract: In the title compound, [Ni(C3H10N2)3][Pt(CN)4], the [Pt(CN)4]2- anion with the environment of the PtII atom, lying on a mirror plane, is square planar, whereas the NiII atom in the [Ni(C3N2H10)3]2+ cation, also lying on a mirror plane, has a slightly distorted octahedral coordination geometry. Three chiral 1,2-diaminopropane molecules, which are disordered equally over two sets of positions, adopt [Delta]([delta][delta][delta]) and [Delta]([lambda][lambda][lambda]) configurations. The average Ni-N and Pt-C bond lengths are 2.131 (10) and 1.988 (10) Å, respectively. The cations and anions are connected by N-H...N hydrogen bonds.
