CoII, FeII, and RuII complexes where the octahedral metal is bound in a N6 bis-terpyridine coordination sphere. All four complexes ([MII(Lpyrtz-tpy)2](X)2 where MII = FeII, RuII, CoII with X = BF4–, or MII = CoII with X = PF6–) were structurally characterized confirming the expected bis-terpyridine coordination sphere. The monometallic complexes all show reversible MII/III redox processes, while the
