Spectroscopic and Structural Properties of Binuclear Platinum-TerpyridineComplexes

摘要

Binuclear platinum-terpyridine (tpy) complexes have been prepared with a varietyof bridging ligands resulting in a range of metal-metal distances (2.998(2) to 3.342(3) A). The energy of an intense visible absorption is strongly dependent on this metal-metal separation and is assigned to a d sigma *(Pt2) yield pi*(tpy) transition.
