Abstract
[Pt2(bpy)2(piam)2]2+ (bpy = bipyridine, piam = pivalamidate) undergoes a metal–metal-to-ligand charge transfer (MMLCT) transition from the destabilised platinum σ* orbital to the bpy π* orbital. A red shift occurs upon dimerisation to [{Pt2(bpy)2(acam)2}2]4+ (acam = acetamidate). We combined [{Pt2(bpy)2(acam)2}2]4+ with [Pt2(pop)4]4− to obtain a one-dimensional chain complex with alternately aligned units. A more pronounced redshift was observed.
