Synthesis, X‐ray Crystal Structures and Electrochemistry of (Indenyl)ruthenium Complexes Containing dppf and Heterocyclic Thiolato/Thione Ligands

Abstract

A number of (indenyl)ruthenium complexes containing dppf [1,1Ј-bis(diphenylphosphanyl)ferrocene] and heterocyclic thiolato/thione ligands have been synthesized. All the complexes were fully characterized by microanalytical and spectroscopic techniques, together with X-ray diffraction analyses for those containing the benzothiazolato (thiolato) and the thiadiazole (thione) ligands. Cyclic voltammetry (CV) experiments indicated that these complexes can be oxidized in three one-electron processes at positive potentials. Differ-

“…For applications of benzothiazole and its derivatives, see: Petkova et al (2000); Leng et al (2001); Karlsson et al (2003); Ć aleta et al (2009); Tzanopoulou et al (2010). For the use of benzothiazoles in building novel complexes, see: Vuoti et al (2007); Zou et al (2004); Ng et al (2008); Chen et al (2010); For our recent work on the design and synthesis of benzothiazole derivatives, see: Fang et al (2010); Lei et al (2010). For secondary Pb-S bonds, see: Chan & Rossi (1997); Turner et al (2008).…”

“…(Petkova et al, 2000;Leng et al, 2001;Karlsson et al, 2003;Ćaleta et al, 2009). Related structural studies are partly focused on the fact that the benzothiazole ring contains N, S and O as potential donor atoms, which exhibit good coordination capacity, and so are propitious to build novel complexes (Zou et al,2004;Vuoti et al, 2007;Ng et al, 2008;Chen et al,2010;). By reviewing their metal complexes (Cambridge Structural Datebase, Version of 5.31 of August 2010; Allen, 2002), it was found that most metal atoms only match with N atom of thiazole ring, but not the S atom (because the coordination capacity of S is much weaker than N), as long as these metal atoms have interaction with the thiazole ring.…”

New mercury(II) halide complexes with neutral ferrocene functionalized thiazolidine‐2‐thiones: Crystallographic and computational analyses

“…Hence, a variety of heterocyclic thione ligands have been used to synthesize coordination complexes with different transition metals such as Cu, [ 6,15 ] Ag, [ 16 ] Cd, [ 17 ] Ru, [ 18 ] and Hg, [ 19 ] as well as main group metals like Sb. [ 20 ] Despite many reports of coordination complexes of this class of ligands, thiones with N ‐substituted 5 membered –NCS 2 – heterocyclic ring systems existing in 1,3‐thiazolidine‐2‐thione/2‐mercapto‐thiazolidine have not been investigated extensively.…”
