To check thestructural integrity of the thus-prepared complexes 1−5, PXRDwas carried out. The PXRD patterns of 1−5 were in goodagreement with the simulated patterns from their crystal data(Figure S22). The thermal stabilities of 1−5 were conductedthrough TGA experiments from RT to 800 °C with a heatingrate of 10 °C·min −1 under a N 2 atmosphere (Figure S23).TGA of 1 shows a weight loss of 22.2% (calcd: 22.8%)between 25−280 °C, which accounts for the liberation of twocoordinated DMF and two MeOH molecules. Complex 2decomposes until about 200 °C (weight loss for 2: 18.5%).This weight loss fits nicely with the release of two coordinatedpyridine molecules (calcd: 18.2%). For 3, the guest moleculescould be removed at 25−125 °C. Regarding 4, the loss ofMeOH and coordinated DMF molecules below 315 °C (calcd:23.4%) fits well 23.7% weight loss. The release of four H 2 Oand two coordinated DMF molecules (calcd: 23.8%) isresponsible for the initial weight loss of 5 in 25−315 °C(24.2%). However, TGA revealed that complexes 1−5 arethermally stable up to 350 °C and decomposition starts fromthere.
