Abstract

Abstract Treatment of a range of bis (thiourea) ligands with inert organometallic transition- metal ions gives a number of novel complexes that exhibit unusual ligand binding modes and significantly enhanced anion binding ability. The ruthenium (II) complex [Ru (η 6-p- cymene)(κS, S′, NL 3− H)]+(2 b) possesses juxtaposed four-and seven-membered chelate rings and binds anions as both 1: 1 and 2: 1 host guest complexes. The pyridyl bis ( ...
