Abstract: The first of the title compounds, [Fe(C₉H₁₀N₄O)₃]Cl₂·5.5H₂O, is the first structurally characterized homoleptic tris[bis(imidazol-2-yl) ketone]-metal complex to be structurally defined. In the second of the title compounds, [FeCl₂(C₉H₁₀N₄O)₂], a pair of monodentate donors supplants one of the bidentate ligands. In the third complex, [Fe₂Cl₄(C₉H₁₀N₄O)₂]·2CH₃OH, a centrosymmetric binuclear compound with a pair of bridging chloride ligands, the introduction of a third chloro ligand results in five-coordination about each of the metal atoms; the environments of the latter are square pyramidal, with a chloro ligand at the apex and the two bidentate arrays about the base of the pyramid.

Formula: [Fe(C₉H₁₀N₄O)₃]Cl₂·5.5H₂O, [FeCl₂(C₉H₁₀N₄O)₂] and [Fe₂Cl₄(C₉H₁₀N₄O)₂]·2CH₄O
