Abstract: Metal–organic frameworks with high stability have been pursued for many years due to the sustainability requirement for practical applications. However, researchers have had great difficulty synthesizing chemically ultra-stable, highly porous metal–organic frameworks in the form of crystalline solids, especially as single crystals. Here we present a kinetically tuned dimensional augmentation synthetic route for the preparation of highly crystalline and extremely robust metal–organic frameworks with a preserved metal cluster core. Through this versatile synthetic route, we obtain large single crystals of 34 different iron-containing metal–organic frameworks. Among them, PCN-250(Fe2Co) exhibits high volumetric uptake of ​hydrogen and ​methane, and is also stable in ​water and aqueous solutions with a wide range of pH values.
