Abstract

Treatment of 5,5′-di(trifluoromethyl)-3,3′-bipyrazole (BipzH₂) with cis-[RuCl₂(Bipy)₂]·2H₂O (Bipy = 2,2′-bipyridine) or cis-[RuCl₂(Dmbipy)₂]·2H₂O (Dmbpy = 4,4′-dimethyl-2,2′-bipyridine) afforded two charge-neutral ruthenium(II) complexes [Ru(Bipz)(Bipy)₂] (I) and [Ru(Bipz)(Dmbipy)₂] (II), respectively. Reactions of 3-trifluoromethyl-5-(2-pyridyl)pyrazole (PypzH) and cis-[RuCl₂(Bipy)₂]·2H₂O or cis-[RuCl₂(Dmbipy)₂]·2H₂O in the presence of NH₄PF₆ produced two cationic ruthenium(II) complexes [Ru(Pypz)(Bipy)₂](PF₆) (III) and [Ru(Pypz)(Dmbipy)₂](PF₆) (IV), respectively. Four complexes were spectroscopically characterized by FTIR, UV-Vis and luminescence. The structures of I·H₂O, III·H₂O and IV have been also determined by single-crystal X-ray diffraction (CIF files CCDC nos. 1935282–1935284, respectively).
