摘要：

Treatment of 5,5'-di(trifluoromethyl)-3,3'-bipyrazole (BipzH(2)) with cis-[RuCl2(Bipy)(2)]center dot 2H(2)O (Bipy = 2,2'-bipyridine) or cis-[RuCl2(Dmbipy)(2)]center dot 2H(2)O (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)]center dot 2H(2)O or cis-[RuCl2(Dmbipy)(2)]center dot 2H(2)O 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 center dot H2O, III center dot H2O and IV have been also determined by single-crystal X-ray diffraction (CIF files CCDC nos. 1935282-1935284, respectively).
