A stable framework has been constructed through multiple charge‐assisted H‐bonds between cationic coordination cages and chloride ions. The framework maintained its original structure upon desolvation, which has been established by single‐crystal structure analysis. This is the first fully characterized stable porous framework based on coordination cages after desolvation, with a moderately high Brunauer–Emmett–Teller (BET) surface area of 1201 m 2 g −1 . This work will not only give a light to construct stable porous frameworks based on coordination cages and thus broaden their applications, but will also provide a new avenue to the assembly of other porous materials such as porous organic cages and hydrogen‐bonded organic frameworks (HOFs) through non covalent bonds.
