Diaqua-1κO,3κO-di-μ-cyanido-1:2κN:C;2:3κC:N-dicyanido-2κC-bis-{4,4'-dibromo-2,2'-[propane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolato}-1κO,N,N',O';3κO,N,N',O'-1,3-di-iron(III)-2-nickel(II).

The title compound, [Fe(2)Ni(C(17)H(14)Br(2)N(2)O(2))(2)(CN)(4)(H(2)O)(2)] or [{Fe(C(17)H(14)Br(2)N(2)O(2))(H(2)O)}(2)(μ-CN)(2){Ni(CN)(2)}], is iso-structural with its Mn(III)-containing analogue. Each Fe(III) atom is chelated by a Schiff base ligand via two N and two O atoms and is additionally coordinated by a water mol-ecule, forming a slightly distorted octa-hedral geometry. The two Fe(III) centres are bridged by a square-planar Ni(CN)(4) unit, which lies on an inversion centre. A two-dimensional network is formed via O-H⋯O and O-H⋯N hydrogen bonds.
