Prior to this work, the only mode of synthesis was oxidizing mixtures of MnIIX2 and PR3 with dry air, but these procedures give low yields and variable outcomes. By taking advantage of the starting material [MnIIICl3(OPPh3)2] (1) and other new strategies, we present robust synthetic protocols for both new and known Mn(III) halido phosphine complexes. In addition to [MnIIIX3(PR3)2], these include [MnIIICl2(dmpe)2]+ salts anInorganic chemistrySynthesis of Mn(III)X3 (X = Cl, Br, I) Compounds with Phosphine (R3P) Ligands.PMC11648271R21-GM141685-01CHE-1847933MacMillan SNSaju ACrawley MRPaul SCohen CLacy DCfalseSynthesis of Mn(III)X3 (X = Cl, Br, I) Compounds with Phosphine (R3P) Ligands.This work details the synthesis and characterization of complexes of the form [MnIIIX3(PR3)2] (X = Cl, Br, I), which is a rare type of coordination compound.
