title: Tris(propane-1,2-diamine-κN,N')nickel(II) tetra-cyanidoplatinate(II).
abstract: 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 octa-hedral coordination geometry. Three chiral 1,2-diamino-propane mol-ecules, 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.
