ABSTRACT
A unique trivalent manganese siloxide complex, blue-violet MnIIILi2Cl[(Ph2SiO)2O]2(THF)4·2THF (3) has been prepared by a straightforward two-step synthetic protocol. Lithiation of (Ph2SiOH)2O (1) followed by reaction with MnCl2(THF)2 gave the structurally remarkable Mn(ii) precursor MnIILi4Cl2[(Ph2SiO)2O]2(THF)5·2THF (2). Surprisingly, the final oxidation step could be achieved using KMnO4 in THF to provide the Mn(iii) species 3 in high yield (91%). Both title compounds were structurally characterized by single-crystal X-ray diffraction.
