The X-ray crystal structure of µ4-Oxo-hexa-µ-iodotetrakis[tripropylphosphinemanganese(II)], a manganese(II) cluster derived from the interaction of di-iodotripropylphosphinemanganese(II) with dioxygen

Abstract

Exposure of an n-pentane solution of MnI₂(PPrⁿ₃) to a trace amount of anhydrous dioxygen at room temperature leads to the isolation of MnI₂(PPrⁿ₃)₂ and Mn₄OI₆(PPrⁿ₃)₄; the latter consists of a tetrahedron of manganese atoms held together by one µ₄-bridging oxygen and six µ-bridging iodine atoms, the five co-ordination about the manganese atoms being completed by capping tri-n-propylphosphine ligands.
