The chemistry of d-block metal–metal multiple bonds has been extensively investigated in the past 5 decades. However, the synthesis and characterization of species with f-block metal–metal multiple bonds are significantly more challenging and such species remain extremely rare. Here, we report the identification of a uranium–rhodium triple bond in a heterometallic cluster, which was synthesized under routine conditions. The uranium–rhodium triple-bond length of 2.31 Å in this cluster is only 3% longer than the sum of the covalent triple-bond radii of uranium and rhodium (2.24 Å). Computational studies reveal that the nature of this uranium–rhodium triple bond is 1 covalent bond with 2 rhodium-to-uranium dative bonds. This heterometallic cluster represents a species with f-block metal–metal triple bond structurally authenticated by X-ray diffraction. These studies not only demonstrate the authenticity of the uranium–metal triple bond, but also provide a possibility for the synthesis of other f-block metal–metal multiple bonds. We expect that this work may further our understanding of the bonding between uranium and transition metals, which may help to design new d-f heterometallic catalysts with uranium–metal bonds for small-molecule activation and to promote the utilization of abundant depleted uranium resources.

The reaction of the metal–metal bonded complex Re2(CO)10 with Cp2Zr(PPh2)2 results in formation of the diphosphido bridged heterobimetallic species, Cp2Zr(μ-PPh2)2ReH(CO)3, 1. Complex 1 crystallizes in the space group P21/c with a = 17.393(3) Å, b = 14.348(7) Å, c = 13.036(3) Å, β = 92.35(2)°, Z = 4, and V = 3250(2) Å3. The crystallographic study confirmed that complex 1 contains two phosphido bridges between the Zr and Re centres. The Zr—P bond distances are 2.629(3) and 2.615(3) Å, while the Re—P bonds are 2.498(3) and 2.474(3) Å. The Zr—Re separation is 3.274(1) Å. The details of the geometry of the ZrP2Re core are discussed in relation to that of other diphosphido bridged early/late heterobimetallics. The possibility of dative bonding between the electron-rich, late metal and the electron-deficient early metal centre is discussed. The data indicate that if such dative bond is present in the d0–d6 complex 1, it is very weak. Keywords: rhenium, zirconium, heterobimetallic, crystal structure.
