Notes. Reaction of manganese(II) arsine oxide complexes with sulphur dioxide: some unexpected products. The X-ray crystal structure of [(Ph3AsO)2H]I3

Abstract

The reaction of [Mn(OAsPh3)4I2] with sulphur dioxide in toluene yields [Mn(OAsPh3)3(O2SI)2)]. Two unexpected products, [(Ph3AsO)2H]I3 and [AsPh3I]I3, have been isolated from the reaction filtrate. The molecular structure of [(Ph3AsO)2H]I3 has been determined by single-crystal X-ray diffraction techniques.
