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]
