The exploitation of advanced porous materials is becoming an important and challenging task for innovative adsorption separation technology. Herein, a new metal\u2010organic framework (MOF)\u2010Zn\u2010ODIP is created through the differentiated coordination patterns of organic ligands and inorganic units. Its unique structure contains two different secondary building units (SBUs), forming different symmetries of hierarchical cages.
