Metal–organic polyhedra (MOPs) are increasingly studied as host–guest capsules, linked into networks, or incorporated into composite materials. As such, understanding the decomposition of MOP structures is of fundamental importance. The degradation of the ubiquitous copper(II) MOP Cu24[5-(hydroxy)isophthalate]24(1) is studied in liquid water. At different intervals of water exposure, powder X-ray diffraction (PXRD) is performed and stepwise conversion of the MOP into three different coordination polymers is observed. First, the formation of a 2D coordination polymer, 2, is observed, which upon further exposure gives a 1D coordination polymer, 3, and finally a trinuclear copper(II) complex, 4. Compound 2is characterized by PXRD owing to its transient nature, while 3and 4are characterized crystallographically. The final structure, 4, contains copper(II) trimers, and so its magnetic behavior is also investigated. |
