Neptunium is an actinide element sourced from anthropogenic production, and, unlike naturally abundant uranium, its coordination chemistry is not well developed in all accessible oxidation states. High-valent neptunium generally requires stabilization from at least one metal-ligand multiple bond, and departing from this structural motif poses a considerable challenge. Here we report a tetrahedral molecular neptunium(V) complex ([Np5+ (NPC)4 ][B(ArF5 )4 ], 1-Np) (NPC = [NPt Bu(pyrr)2 ]- ; t Bu = C(CH3 )3 ; pyrr = pyrrolidinyl (N(C2 H4 )2 ); B(ArF5 )4 = tetrakis(2,3,4,5,6-pentafluourophenyl)borate)...
