MetalloligandsL1andL2consisting of directional bis(terpyridine)ruthenium(II) units and bipyridine moieties were constructed by amide formation. From these metalloligands two Ru–Pt heterobimetallic complexes1and2were derived by a building‐block method by means of platination with [PtCl2(dmso)2]. Both bimetallic complexes1and2feature metal‐to‐ligand charge transfer (MLCT) absorptions, and emission occurs at room temperature in fluid solution from3MLCT(Ru) states in all cases. Energy transfer from platinum to ruthenium is observed in2but not in1(light harvesting). The one‐electron‐reduced species [1]–and [2]–were prepared by reduction of1and2with decamethylcobaltocene. EPR spectra and DFT calculations reveal that the spin density is localized at the tpy–CO/Ru (tpy = terpyridine) site in [1]–, whereas it is centered at bpy–CO/Pt (bpy = 2,2′‐bipyridine) in [2]–. Efficient photoinduced electron transfer from triethanolamine to1and2is feasible by excitation at 500 nm [MLCT(Ru)].
