Transition-metal-bridged bimetallic clusters with multiple uranium–metal bonds

Transition-metal-bridged bimetallic clusters with multiple uranium–metal bonds, Published online: 28 January 2019; doi:10.1038/s41557-018-0195-4

Heterometallic clusters have shown promise in catalysis and small-molecule activation, but species comprising uranium–metal bonds have remained difficult to synthesize. Now, facile reactions between uranium and nickel precursors have led to nickel-bridged diuranium clusters supported by a heptadentate N4P3 scaffold. Computational analysis points to an unusual electronic configuration for uranium, U(iii)-5f26d1.
