N2 - A select club: The polyoxometalate [(γ-SiW10O 32)2(μ-O)4]8- (18-) has a cavity that can sizeselectively encapsulate the ions Pb2+, Sr2+, Na+, Ag+, K+, and Rb + (see picture, light blue; Si hidden, W gray, O red). Larger Ba 2+ and Cs+ ions (pink) are not encapsulated by 1. The molecular structures of [Mn+∪1](8-n)- (M n+=Pb2+, Sr2+, Ag+, Ba2+) were characterized by X-ray crystallography.
