The development of materials that reversibly store high densities of thermal energy is critical to the more efficient and sustainable utilization of energy. Herein, we investigate metal–organic compounds as a new class of solid–liquid phase-change materials (PCMs) for thermal energy storage. Specifically, we show that isostructural series of divalent …
