title: Diaqua-(5,5,7,12,12,14-hexa-methyl-1,4,8,11-tetra-azacyclo-tetra-deca-ne)nickel(II) tetra-cyanidonickelate(II).
abstract: In the title complex, [Ni(C(16)H(36)N(4))(H(2)O)(2)][Ni(CN)(4)], the [Ni(teta)(H(2)O)(2)](2+) cations (teta = 5,5,7,12,12,14-hexa-methyl-1,4,8,11-tetra-azacyclo-tetra-deca-ne) and [Ni(CN)(4)](2-) anions are arranged in an alternating fashion through electrostatic and N-H⋯N and O-H⋯N hydrogen-bonding inter-actions, forming a two-dimensional layered structure. Adjacent layers are linked through weak van der Waals inter-actions, resulting in a three-dimensional supra-molecular network.
