Iron(III) complexes of the metalloligand [Pt2(μ-S)2(PPh3)4]

► Synthesis of the first isolated iron complexes of [Pt2(m-S)2(PPh3)4]. ► Methodology involved air-oxidation of Fe(II) derivatives, monitored by ESI MS. ► X-ray structure shows coordination at Fe to be distorted towards trigonal prismatic. ► Magnetic measurements confirm high-spin iron(III).
