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 Δ(δδδ) and Δ(λλλ) 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.
