The effective incorporation of more than one metal into metal-organic frameworks (MOFs) has shown to be greatly influential in improving functionality of MOFs in various applications such as, electrocatalysis, separation, gas storage, energy conversion and storage. The tunabilty, modularity, and crystallinity properties of MOFs make the preparation of desirable heterometallic systems possible. Particularly interesting is the incorporation of different metals through metal node engineering; a technique that retains the intrinsic porosity of the MOF.<br/>Herein, we investigate the possibility of tuning the electronic properties of actinide containing and non-actinide containing heterometallic MOFs through metal node design in three distinct classes of MOF systems. Furthermore, we demonstrate the unprecedented water stability as well as structural dynamism of the actinide-based systems on exposure to external stimuli. Comprehensive characterization techniques and studies of the novel heterometallic multinuclear MOFs, for example, single crystal and powder X-ray diffraction as well as X-ray photoelectron spectroscopy, reveal not just the structure-property relationship of these systems, but also present fundamental knowledge for the development of novel hierarchical forms for effective nuclear waste management.<br/>
