Coinage clusters : A stepwise construction with tetraphosphine ligands (dpmppm) afforded a series of octanuclear coinage rings (see figure); the shape and size of the rings vary depending on the element M and the counteranions. The {Au I 2 Ag I Cu I } 2 ring notably incorporates a BF 4 − anion in the open pocket surrounded by phenyl groups, even in solution.
