Structural insight into halide-coordinated [Fe₄S₄X_nY_4−n]²⁻ clusters (X, Y = Cl, Br, I) by XRD and Mössbauer spectroscopy

Abstract

Iron sulphur halide clusters [Fe4S4Br4]2‒ and [Fe4S4X2Y2]2‒ (X, Y = Cl, Br, I) were obtained in excellent yields (77 to 78%) and purity from [Fe(CO)5], elemental sulphur, I2 and benzyltrimethylammonium...
