Abstract: The title compound, [Cr₂Cl₂O(C₁₈H₁₈N₄)₂](PF₆)₂, is isostructural with the V^III analogue. Each Cr^III atom is chelated by the tetradentate tris(2-pyridylmethyl)amine ligand via four N atoms, and further coordinated by one Cl atom and one bridging O atom, giving a slightly distorted octahedral coordination geometry. The dinuclear complex is centrosymmetric, with the bridging O atom lying on a centre of inversion.
