文摘

Nitrosylruthenium complexes containing 2,2':6',2' '-terpyridine (terpy) have been synthesized and characterized.The three alkoxo complexes trans-(NO, OCH₃), cis-(Cl, OCH₃)-[RuCl(OCH₃)(NO)(terpy)]PF₆ ([2]PF₆), trans-(NO,OC₂H₅), cis-(Cl, OC₂H₅)-[RuCl(OC₂H₅)(NO)(terpy)]PF₆ ([3]PF₆), and [RuCl(OC₃H₇)(NO)(terpy)]PF₆ ([4]PF₆) weresynthesized by reactions of trans-(Cl, Cl), cis-(NO, Cl)-[RuCl₂(NO)(terpy)]PF₆ ([1]PF₆) with NaOCH₃ in CH₃OH,C₂H₅OH, and C₃H₇OH, respectively. Reactions of [3]PF₆ with an acid such as hydrochloric acid andtrifluoromethansulforic acid afford nitrosyl complexes in which the alkoxo ligand is substituted. The geometricalisomer of [1]PF₆, trans-(NO, Cl), cis-(Cl, Cl)-[RuCl₂(NO)(terpy)]PF₆ ([5]PF₆), was obtained by the reaction of [3]PF₆in a hydrochloric acid solution. Reaction of [3]PF₆ with trifluoromethansulforic acid in CH₃CN gave trans-(NO, Cl),cis-(CH₃CN, Cl)-[RuCl(CH₃CN)(NO)(terpy)]²⁺ ([6]²⁺) under refluxing conditions. The structures of [3]PF₆, [4]PF₆·CH₃CN, [5]CF₃SO₃, and [6](PF₆)₂ were determined by X-ray crystallograpy.
