We describe a ruthenium-based coordination cage, whose geometry and topology can be altered dramatically by using two closely related solvents: chloroform and dichloromethane. In chloroform, we observe an octanuclear prismatic cage, whereas a tetranuclear complex is formed in dichloromethane. The basis of this unusual solvent-sensitivity is the incorporation of metallacrown recognition units into a flexible, kinetically labile nanostructure.en10.1039/c1sc00779cinfo:eu-repo/semantics/closedAccessArticle33701704WOS:000299949500005Q1Q1
