摘要：

Molecular (DME)(2)Tm(SC6F5)(3) and tetrametallic (DME)(4)(mu(2)-SPh)(8)Tm-4(SPh)(4) have been isolated in high yield and characterized by conventional methods. The fluorinated thiolate has an eight-coordinate Tm(M) 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)angstrom 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(M) ions. Emission properties of both thiolates and the chalcogen-fich cluster (THF)(6)Tm4Se9(SC6F5)(2) have been established. The Ph compound is significantly more emissive than either of the fluorinated species.
