Abstract

The new iron-thiolate complex [CpFe(dppe)SC 6H 4OH]PF 6 (1), prepared by the oxidative addition of CpFe(dppe)I (2) to HSC 6H 4OH (3), reacts in one step with N 3P 3Cl 6 (4) in acetone to give the hexanuclear iron-triolate complex N 3P 3[CpFe(dppe)SC 6H 4O] 6 (5), the first cyclotriphosphazene containing thiolate groups coordinated to a metal. Electrochemical data suggest the absence of electronic communication between the iron centers. Magnetic properties for the new complexes are discussed.
