Tris(propane-1,2-diamine-κ(2) N,N′)nickel(II) tetra­cyanidoplatinate(II)

In the title compound, [Ni(C(3)H(10)N(2))(3)][Pt(CN)(4)], the [Pt(CN)(4)](2−) anion with the environment of the Pt(II) atom, lying on a mirror plane, is square planar, whereas the Ni(II) atom in the [Ni(C(3)N(2)H(10))(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.
