}Extensive chemical, spectrophotometric, and x-ray structural studies have shown that trivalent rhenium is strongly homophilic—that is, it tends to form bonds to other Re111 atoms—and it forms at least three different series of [ReX4]nn- complexes. The mononuclear, square complex, [ReBr4]-, adds two water molecules to give trans-[ReBr4(H2O)2]-. The binuclear complexes [Re2Cl8]2- and [Re2Br8]2- have strong Re-Re bonds, unsupported by halide bridges. The trinuclear species, [Re3X12]3- or Re3X9L3…

The natural tendency of a uranium atom to be preferentially complexed by a ligand, rather than to explicitly form a direct U U bond, has to date precluded the isolation of stable uranium species exhibiting direct metal–metal bonding, and uranium seems nevertheless to be a promising candidate to form multiply bonded species in actinide chemistry.
