A Rock‐Salt‐Like Lattice Structure Consisting of Monocationic and Monoanionic Au^IAg^ICu^II Supramolecular Cages of <scp>D</scp>‐Penicillaminate

Abstract

All three coinage metals are present in the supramolecular compound created from D-penicillamine (D-H2pen) by stepwise reaction with AuI, AgI, and CuII in the presence of Cl−. In this compound, 20-nuclear monocationic [Au6Ag8Cu6Cl(H2O)5(D-pen)12]+ and 21-nuclear monoanionic [Au6Ag9Cu6Cl4(H2O)6(D-pen)12]− (see picture) supramolecular cages, each of which accommodates a Cl− ion (green), are linked so as to form a giant rock-salt-like lattice structure.
