ABSTRACT: The asymmetric unit of the title compound, {[Cu(2)Fe(CN)(6)(C(2)H(8)N(2))(4)]·4.5H(2)O}(n), consists of two [Cu(C(2)H(8)N(2))(2)](2+) cations, one [Fe(CN)(6)](4-) anion, four water mol-ecules and a half water mol-ecule that lies on a twofold rotation axis. The Fe(II) atom is coordinated by six C atoms from three terminal and three doubly bridging CN(-) ligands. The bridging CN(-) ligands connect the anion to a five-coordinate [Cu(C(2)H(8)N(2))(2)](2+) cation and to two symmetry-related six-coordinate [Cu(C(2)H(8)N(2))(2)](2+) cations, forming a one-dimensional polymer in the ab plane. Inter-molecular hydrogen bonds connect the polymer units into a three-dimensional network.
