The fracture mechanism of zeolitic imidazolate framework (ZIF) glasses is revealed to be associated with bond switching organic linkers around central Zn nodes. more pronounced for ZIF smaller linkers.

Zeolitic imidazolate frameworks of zinc, cobalt, and cadmium, including the framework ZIF-8 commercially sold as Basolite Z1200, exhibit surprising sensitivity to carbon dioxide under mild conditions. The frameworks chemically react with CO2 in the presence of moisture or liquid water to form carbonates. This effect, which has been previously not reported in metal-organic framework chemistry, p...
