Searching novel haloplumbate building units to construct three‐dimensional (3D) frameworks is very important and highly desirable because such materials would possess new physical properties and potential applications. Here, by employing tetrakis( N ‐imidazolemethylene)methane(TIMM) as a structure‐directing agent, the first 3D haloplumbate framework constructed from unprecedented Lindqvist‐like highly coordinated [Pb 6 Br 25 ] 13− nanoclusters has been successfully prepared under hydrothermal condition, where all Pb 2+ centres in [Pb 6 Br 25 ] 13− nanoclusters adopt seven‐/eight‐coordinated configurations. The as‐obtained material is a wide‐gap semiconductor (≈3.1 eV) and can be stable up to 320 °C. More importantly, this material has been demonstrated to show temperature‐dependent emission. Our results could provide a new strategy to explore novel metal–halide open‐framework materials.
