Description
Summary:Integrated but separate: A strongly nucleophilic cluster surface allows the selective complexation and separation of ammonium and potassium ions. Six {Mo4VKO6} rings with crown‐ether‐like functionality (see picture; Mo blue, V green, K pink, O red) present in the holes of the investigated cluster complex integrate six ammonium ions (N orange, H yellow).
