Fig. 4: Structures and mechanistic interconversion of [Fe8S8]m+ (m = 2, 4, 6) clusters.

From: Stepwise and reversible assembly of [2Fe–2S] rhombs to [8Fe–8S] clusters and their topological interconversions

Fig. 4

a–c, Solid-state molecular structures of ebdc (a), lbdc (b) and ildc (c) in crystals of K4[Fe8S8(DmpS)6]·3.5(C7H8), [Fe8S8(DmpS)6]·3(C7H8) and [Fe8S8(DmpS)4], respectively. Displacement ellipsoids are shown at the 50% probability level for ebdc and ildc, and at 30% for lbdc, and are only displayed for the Fe, S and K atoms. Cocrystallized solvent molecules and hydrogen atoms have been omitted for clarity. d, Proposed mechanism for the interconversions of the three Fe8S8 clusters (ebdc, lbdc and ildc). Structures marked by a double dagger are postulated transition states.
