title: Diaquabis(ethylenediamine)copper(II) bis[tris(ethylenediamine)nickel(II)] tris(naphthalene-2,6-disulfonate) tetrahydrate.
abstract: The title mixed-metal compound, [Cu(C(2)H(8)N(2))(2)(H(2)O)(2)][Ni(C(2)H(8)N(2))(3)](2)(C(10)H(6)O(6)S(2))(3).4H(2)O, was obtained during investigations of the porous frameworks constructed by amino-coordinated metal complex cations and large organic anions. All three naphthalene-2,6-disulfonate anions and the [Cu(en)(2)(H(2)O)(2)](2+) cation are located on crystallographic inversion centers and assemble into an extended two-dimensional network through intermolecular hydrogen bonds, creating cavities in which the [Ni(en)(3)](2+) cations and water molecules are included.
