Abstract

Co-crystallization in supramolecular complexes often encounters significant challenges, particularly when dealing with highly charged ionic species. One major issue is that the parent complex structure may decompose during the process, while the new structure cannot be obtained using the original method. In this study, we reported the formation of new coordination complexes derived from the decomposition of a framework structure composed of [AuI6AgI3CuII3(tdme)2(D-pen)6(H2O)3]3+. Two decomposition products, [AuI6AgI2CuII2(tdme)2(D-pen)6] and [AuI6AgI2CuII2(tdme)2(D-pen)6][AuI6CuII3(tdme)2(D-pen)6], were isolated as a result of the interruption of [RhII4ZnII4O(L-cys)12]6- through anion-exchange reaction at two different temperature conditions (0 and 25oC) in a co-crystallization process.
