A new class of supramolecular organometallic gels with a discrete rhomboidal metallacycle as the main skeleton was fabricated through hierarchical self‐assembly (see figure). More importantly, by taking advantage of the dynamic nature of metal–ligand bonds, the stimuli‐responsive gel–sol transition of the obtained gels was realized by disassembly and reassembly of the rhomboidal scaffold as controlled by bromide anions.
