title: Complexing ability of the versatile, redox-active, 3-[3-(diphenylphosphino)propylthio]-3',4,4'-trimethyl-tetrathiafulvalene ligand.
abstract: The synthesis of a ligand containing as an electroactive core a tetrathiafulvalene moiety, 3-[3-(diphenylphosphino)propylthio]-3',4,4'-trimethyl-tetrathiafulvalene, is reported. Its versatile ability to act as a bidentate or a monodentate ligand, as demonstrated by the metal carbonyl complexes obtained, is described. The novel cis-Mo(CO)(4)(P-TTF)(2) 4 and cis-W(CO)(4)(P,S-TTF) 6 complexes have been characterized by X-ray diffraction analyses and cyclic voltammetry measurements. Within complex 4, no significant influence of the two electroactive ligands on the molybdenum center was detected, whereas, in complex 6, a weak influence of the TTF redox-active core can be observed on the redox behavior of the metal center.
