Terphenylgermanium Ar*Ge [Ar*=CH(2,6-Trip), Trip=2,4,6-CHiPr] was found to act as a novel μ-Ge-bis(hexahapto-Trip) bridging ligand. Deprotonated terphenyl germanium trihydride [Li(thf)][Ar*GeH] (1) undergoes reductive elimination and transfer of hydrogen in reaction with dimeric [(COD)RhCl] to yield the dinuclear complex [Ar*GeRh(COE)RhCl(COD)] (2). Subsequent chloride abstraction from compound 2 using Na[BAr ] or Li[Al(OBu)] results in the cationic complexes [Ar*GeRh(COE)Rh(COD)][WCA] (3) {WCA: [BAr ] (Ar=CH-3,5-(CF)), [Al(OBu)]}.

ConspectusAlkenes and alkynes are fundamental building blocks in organic synthesis due to their commercial availability, bench-stability, and easy preparation. Selective functionalization of alkenes and alkynes is a crucial step for the synthesis of value-added compounds. Precise control over these reactions allows efficient construction of complex molecules with new functionalities.

A carbon-rich molecule is synthesized, which mainly contains conjugated sp and sp hybridized carbon centers. Alkenyl and alkynyl binding sites are arranged such that this compound serves as ligand to a binuclear metal unit with a Rh─Rh bond. Furthermore, CH units are placed in proximity to the metal centers.

Pathway selection principles in reversible reaction networks such as molecular self-assembly have not been established yet, because achieving kinetic control in reversible reaction networks is more complicated than in irreversible ones. In this study, we discovered that coordination squares consisting of cis-protected dinuclear rhodium(II) corner complexes and linear ditopic ligands are assembled under kinetic control, perfectly preventing the corresponding triangles, by modulating their energy landscapes with a weak monotopic carboxylate ligand (2,6-dichlorobenzoate: dcb) as the leaving ligand. Experimental and numerical approaches revealed the self-assembly pathway where the cyclization step to form the triangular complex is blocked by dcb.
