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… 

Dinuclear and Mononuclear Rhenium Coordination Compounds upon Employment of a Schiff-Base Triol Ligand: Structural, Magnetic, and Computational Studies.

Investigation of the magnetic properties revealed a Curie paramagnetic behavior (S = 1/2) with a pronounced temperature independent paramagnetism (TIP) for 1·2C7H8 and 2.3%, confirming the triplet and doublet spin ground state of the complexes and establishing an electron-rich σ2π4δ1δ*1 bond order of 3 for 1 ·2C 7H8.

The complex Re2Cl6(P-n-Bu3)2 prepared in situ reacts with CH3CN to form a blue-green solution. Addition of the chelating phosphine bis(diphenylphosphino)methane (dppm) results in the formation of the

Quantum chemical calculations predict the diphenyl diuranium compound [PhUUPh] to have a stable 1Ag ground state.

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.

Heterometallic Clusters with Multiple Rare Earth Metal-Transition Metal Bonding.

The identification of the first example of a molecule containing multiple RE-Rh bonds is presented, providing a possible route for the construction of complexes with multiple RE metal-metal bonds and an investigation of their potential properties and applications.
