title: Tris(propane-1,2-diamine-κN,N')nickel(II) tetra-cyanidonickelate(II).
abstract: The title compound, [Ni(C(3)H(10)N(2))(3)][Ni(CN)(4)], is built up of [Ni(pn)(3)](2+) cations (pn is 1,2-diamino-propane) and [Ni(CN)(4)](2-) anions. Both Ni(II) atoms in the cation and the anion lie on a mirror plane. The respective ions inter-act through Coulombic forces and through a complex network of hydrogen bonds. Extended disorder associated with the cation has been resolved. The occupancies of the respective disordered positions are 0.4:0.4:0.2.
