Ruthenium biimidazole complexes as anion receptors†
Abstract
The behavior of the compound [RuCl(cym)(H2biim)][BAr′4] (cym = η6-para-isopropylmethylbenzene, Ar′ = 3,5-bis(trifluoromethyl)phenyl), synthesized from [{RuCl(cym)}2(µ-Cl)2], H2biim and NaBAr′4, has been studied as a receptor of anions both in solution and in the solid state.
