based on cubane Cu4I4 clusters. Crystal-to-crystal transformations of CPs 1–6 were reversible under heat or in an appropriate solvent (acetonitrile, dichloromethane, chloroform, or benzene). In addition, crystal transformations between CPs 1 and 3 occurred through addition of L or CuI. Moreover, CPs 3–6 exhibited reversible guest exchange and crystal transformations on exposure to the vapor of volatile
