The most stable [Al(DMSO2)3]3+ complex cation in dimethyl sulfone (DMSO2, (CH3)2SO2) has D3 symmetry with twofold axes in Al-S lines coincident with the twofold rotation axes of mutually turned DMSO2 ligands by ca 60°. The central Al atom is hexacoordinated by six O atoms with nearly octahedral coordination. More than one electron is transferred to the Al central atom from DMSO2 ligands. Weaker and longer S-O, stronger and shorter S-C bonds, lower O-S-O bond angles and greater O-S-C and C-S-C ones in [Al(DMSO2)3]3+ than in free DMSO2 are implied by weak Al-O bonding.
