Abstract
Structural parameters of free and metal coordinated sulfoxides are reviewed and updated average values are derived. For uncoordinated sulfoxides, the average S−O bond distance is 1.4918(9) Å. This value is lengthened to 1.528(1) Å upon O-coordination to metal ions, while it is reduced to 1.4731(6) Å upon S-coordination. The sulfoxide bonding and bridging modes are discussed together with some stereochemical features.
