Chiral inversion around a seven-coordinated cobalt center induced by an interaction between sugars and sulfate anions

Carbohydrates are widely occurring and are needed by living organisms. Naturally rare carbohydrates are involved in glycoproteins, glycolipids and antibiotics. The syntheses and structural determinations of novel seven-coordinated cage-type cobalt(II) compounds, containing N-glycosides from mannose-type aldoses is reported.
