new extended tetrathiafulvalene (TTF) dithiolene ligand substituted with alkyl pyridine groups, pyridylethylsulfanyltetrathiafulvalenedithiolene (pesdt2−), as well as the corresponding gold (III) complex [Au(pesdt)2]− obtained as a tetrabutylammonium salt are described. The oxidation potential of this complex is rather low and the paramagneticneutralcomplex is obtained as an electrically insulating
The preparation of a new bis(2-pyridylethylsulfanyl)-1,3-dithiole-2-one (1) and the first example of a tetra-azo substituted bisdithiolene transition metal complex, Ni(dpesdt)(2) (2) are reported. This complex crystallizes in two polymorphs, one is triclinic, and the other is monoclinic, P2(1)/n space group. (c) 2006 Elsevier B.V. All rights reserved.
