A cyano-bridged trimeric complex [Mn(CH₃OH)₂(H₂O)₂][Fe(bpb)(CN)₂]₂·2H₂O [bpb^2- is 1,2-bis(pyridine-2-carboxamido)benzenate]

Abstract: The structure of the title complex, diaquadi- [mu] -cyano-dicyanodimethanolbis[N,N'-o-phenylenebis(pyridine-2-carboxamidato)]diiron(III)manganese(II), [MnFe₂(C₁₈H₁₂N₄O₂)₂(CN)₄(CH₄O)₂(H₂O)₂]·2H₂O, consists of neutral centrosymmetric [Mn(CH₃OH)₂(H₂O)₂][Fe(bpb)(CN)₂]₂ heterotrinuclear units [bpb^2- = 1,2-bis(pyridine-2-carboxamido)benzene(2-)] and water molecules of crystallization. Each [Fe(bpb)(CN)₂]^- unit acts as a monodentate ligand through one of its two cyanide groups toward the central Mn^II ion (site symmetry $\overline 1$ ) in a bent fashion [C-N-Mn = 159.7 (2)°].
