The first heterobimetallic uranium(IV)/vanadium(III) phosphite compound, Na2UV2(HPO3)(6) (denoted as UVP), was synthesized via an in situ redox-active hydrothermal reaction. It exhibits superior hydrolytic and antioxidant stability compared to the majority of structures containing low-valent uranium or vanadium, further elucidated by first-principles simulations, and therefore shows potential applications in nuclear waste management.
