Publication date: Available online 16 April 2019Source: Journal of Molecular StructureAuthor(s): Hadil Alshurafa, Mohammad El-khateeb, Hassan Abul-Futouh, Helmar Görls, Wolfgang WeigandAbstractCyclopentadienyl ruthenium complexes bearing mixed heterocyclic thiol and bis(diphenylphsphino)ferrocene (dppf) ligands are presented. The complex-salts [CpRu(dppf)(κ1S-HS-het)]PF6 {Cp = η5-C5H5; HS-het = 2-mercaptobenzothiazole (1), 2-mercaptobenzimidazole (2)} were synthesized from the reaction of CpRu(dppf)Cl with the thiol in the presence of KPF6 salt under reflux. Complexes 1 and 2 have been characterized by spectroscopic methods (1H NMR, 31P{1H}-NMR, MS) and elemental analysis. The solid-state structures of [CpRu(dppf)(κ1SS2C7H5N)]PF6 (1) and [CpRu(dppf)(κ1S-SC7H6N2)]PF6 (2) have been determined by X-ray crystallography. The cyclic voltammetry of these two complexes are measured.Graphical abstractThe complex-salts [CpRu(dppf)(κ1S-HS-het)]PF6 {Cp = η5-C5H5; HS-het = 2-mercaptobenzothiazole (1), 2-mercaptobenzimidazole (2)} were synthesized from the reaction of CpRu(dppf)Cl with the thiol in the presence of KPF6 salt under reflux.
