Abstract

Molecular (DME)₂Tm(SC₆F₅)₃ and tetrametallic (DME)₄(M₂-SPh)₈Tm ₄(SPh)₄ have been isolated in high yield and characterized by conventional methods. The fluorinated thiolate has an eight-coordinate Tm(III) ion bound to three sulfur atoms from the thiolates, four oxygen donors from the THF ligands, and a relatively weak dative Tm - F interaction with a 2.842(3)Å Tm-F separation. The benzenethiolate compound crystallizes as a tetramer with an alternating number (3, 2, 3) of thiolates connecting the nearly linear array of Tm(III) ions. Emission properties of both thiolates and the chalcogen-rich cluster (THF)₆Tm₄Se₉(SC ₆F₅)₂ have been established. The Ph compound is significantly more emissive than either of the fluorinated species.
