Fig. 2. — Solid-state molecular structures of 3 (A), 4 (B), 5 (C), 6 (D), and 7 (E) in crystals of K₄[Fe₄S₄(DmpS)₄]⋅2HMDSO, K₃[Fe₄S₄(DmpS)₄]⋅2HMDSO, K₂[Fe₄S₄(DmpS)₄]⋅2HMDSO, K[Fe₄S₄(DmpS)₄]⋅C₇H₈, and [Fe₄S₄(DmpS)₄]⋅HMDSO, respectively. Cocrystallized solvent molecules as well as hydrogen atoms were omitted for clarity. Thermal ellipsoids at the 50% probability level are shown only for the Fe, S, and K atoms. Detailed structural parameters of 3–7 are summarized in SI Appendix, Tables S4–S9 and S11.
