Abstract: In the title compound, [Mn₂Ni(C₁₇H₁₄Br₂N₂O₂)₂(CN)₄(H₂O)₂] or [{Mn(C₁₇H₁₄Br₂N₂O₂)(H₂O)}₂( [mu] -CN)₂{Ni(CN)₂}], each Mn^III atom is chelated by a Schiff base ligand via two N and two O atoms and is additionally coordinated by a water molecule to give a slightly distorted octahedral geometry. Two such Mn^III ions are linked by a square-planar Ni(CN)₄ unit, which lies on an inversion centre. A two-dimensional network is formed by O-HO and O-HN hydrogen bonds.
