The reduction of the bulky 1,2-diketone bis(2,6-diisopropylphenyl)glyoxal (1) and FeBr2 with 1.5 equivalents of Na results in a Class 2 mixed valent H.S. FeII L.S. FeIII complex (2) with two five-coordinate Fe centres which are antiferromagnetically exchange-coupled to give a total spin St = 3/2 ground state and an St = 5/2 excited state that are separated by about 25 cm-1 (for ΔJ ≈ 5J) The Royal Society of Chemistry.
