One-Dimensionally Extended Paddlewheel Dirhodium Complexes from Metal–Metal Bonds with Diplatinum Complexes

We have succeeded in obtaining unique one-dimensional (1D) chain complexes (1, 2, and 3) comprised of two types of metal species: rhodium and platinum. These compounds are constructed from a dinuclear rhodium complex (i.e., [Rh2]) and a pivalamidate-bridged platinum complex (i.e., [Pt2]), forming an attractive quasi-1D infinite chain, expressed as −{[Rh2]–[Pt2]–[Pt2]}n–. Interestingly, the bridging ligands of [Rh2] can be varied with trifluoroacetate, acetate, and acetamidate groups, indicating the possibility of electronic structure modulation in the 1D chain.
