Coordination chemistry at a surface: polymetallic complexes prepared on quartz by alternate deposition of iron(II) and ruthenium(II) centres

Abstract

Polymetallic complexes having well defined geometries are prepared via attachment of an anchor ligand to a quartz surface followed by repeated sequential reaction with [Fe(OH₂)₆]²⁺ and a Ru^II complex having two tridentate bridging ligands rigidly fixed at 180°, [(tpy-ph-tpy)₂Ru]Cl₂[tpy-ph-tpy = 1,4-di(2,2′,6′,2″-terpyridin-4′-yl)benzene].
