Abstract: The title compound, [Fe₂(C₂₃H₃₂B₂N₆O)₂]·2C₄H₈O, features a dinuclear complex located on a centre of inversion. It crystallizes with two molecules of tetrahydrofuran in the asymmetric unit. The molecular conformation of a pseudopolymorph of the title complex with two molecules of toluene in the asymmetric unit is almost identical. It is noteworthy that the hydroxyl H atom is shielded from any classical hydrogen-bond acceptor and there is only a short contact to the centre of an aromatic ring (centroidH = 2.48 Å).
