Running rings around ammonium : Use of amine templates leads to a rich structural chemistry for heterometallic cyclic compounds. For example, use of two diethylammonium cations leads to the formation of the {Cr 10 Cu 2 } cage, which is stabilized by NH⋅⋅⋅F bonds (see picture). The results suggest a new method for making sophisticated polymetallic architectures.
