Simple thermal treatment of three‐dimensional Kagomé‐like [In(OH)(BDC)] n (In–MIL‐68) hexagonal lumps in the presence of an extra amount of 1,4‐benzenedicarboxylic acid (H 2 BDC) induces structural and morphological transformations of the hexagonal lumps into three‐dimensional quartz‐structured [InH(BDC) 2 ] n (QMOF‐2) pointed hexagonal rods. Transformation processes have been monitored by scanning electron microscopy to verify the destruction of the In–MIL‐68‐based hexagonal lumps and the simultaneous reconstruction of QMOF‐2‐based pointed hexagonal rods. We have also discovered the production of In–MIL‐68‐based hexagonal wires as early‐stage kinetic products and the generation of QMOF‐2‐based pointed hexagonal rods as final‐stage thermodynamic products from one‐step solvothermal reaction of In(NO 3 ) 3 with an excess amount of H 2 BDC.
