Abstract
In this study, [{Rh2(O2CCH3)4(OH2)}{Rh2(O2CCH3)4(O2CCF3)}{Pt2(acam)2(bpy)2}2](PF6)3 (2, acam = acetamidate, bpy = 2,2ʹ-bipyridine), a one-dimensional (1D) octanuclear complex aligned as Rh–Rh–Pt–Pt–Pt–Pt–Rh–Rh, was successfully synthesized and characterized. Compound 2 contained a tetranuclear platinum complex where each Pt atom was coordinated with bpy as the co-ligand, exhibiting metal–metal to ligand charge transfer (MMLCT) around 2.0 eV. It admixed with three characteristic bands attributed to heterometallic Pt–Rh bonds in the range of 1.3–2.5 eV. This success paves the way for the development of further novel heterometallic one-dimensional chains containing co-ligands that affect the σ-type orbitals of metal–metal bonds.
