A simple thermal treatment induced transition from Zn3(OH)2(BDC)2 (MOF-69c) to Zn4O(BDC)3 (MOF-5) is reported. Phase crystallinity, pore characteristics and hydrogen storage capacities of the resulting crystals were investigated. It is shown that the structural transition from Zn3(OH)2(BDC)2 (MOF-69c) to Zn4O(BDC)3 (MOF-5) could be induced by simply employing the optimal thermal treatment conditions of 200 °C for 48 h in open air. The resultant relatively lower specific surface area of MOF-5 crystals compared to MOF-69c was in agreement with the increased pore diameter and decreased hydrogen storage capacity at 1 bar and 77 K.
