A new ruthenium biimidazole-like anion receptor featuring two 鈥渃helating鈥?NH鈰疧 intramolecular hydrogen bonds, [Ru(bpy)2(DNBbimH2)](PF6)2 (2路(PF6)2) (bpy = 2,2鈥?bipyridine; DNBbimH2 = 5,5鈥?6,6鈥?tetramethyl-7,7鈥?dinitro-2,2鈥?bibenzimidazole), has been synthesized. Its anion-binding ability towards different anions in acetonitrile has been studied.
