Coarse-grain unactivated manganese powder reacts with Me3Pl2 in diethyl ether to form the polymeric [Mn(PMe3)I2]n complex, I, which reacts with trace quantities of dioxygen to form dinuclear [Mn2(PMe3)3I5]·PMe3, II, the first mixed oxidation state (+2/+3) manganese complex which contains phosphine ligands; both I and II react with an excess of dioxygen to form the monomeric [Mn(PMe3)2I3].
