Bis(triphenylphosphineoxide) manganese(III) chloride is a coordination complex of manganese(III) chloride. Unlike most compounds containing "Mn(III)Cl3", [MnCl3(OPPh3)2] can be stored under normal laboratory conditions.[1] It is a blue, paramagnetic solid.
Synthesis and reactions
[edit]Treatment of meta-stable solutions of Mn(III)Cl3 with triphenylphosphine oxide results in precipitation of solid [MnCl3(OPPh3)2]. This compound was first prepared using the thermally unstable ethereal adduct (dioxane)Mn(III)Cl3.[2] A convenient synthesis starts from Mn(OAc)2, trimethylsilylchloride, and potassium permanganate.[3]
