Abstract

[Extract] The synthesis and physical properties of polymetallic ligandbridged molecular assemblies have been topics of intense interest, motivated by their possible application to photochemical molecular devices. An aspect receiving limited (but increasing) attention is the existence of stereoisomerism within such assemblies and its influence on intramolecular energy and electron transfer processes.

The stereoisomers of the trinuclear Ru2Os species [{Ru(bpy)₂}₂{Os(bpy)₂}(μ-HAT)]⁶⁺ (HAT = 1,4,5,8,9,12-hexaazatriphenylene; bpy =2,2'-bipyridine) have been isolated using a combination of stereoselective syntheses and chromatographic procedures and characterized by NMR and CD spectroscopy.
