The cyclopentadienyl ligand with the (dimethylamino)ethyl substituent has been used in the synthesis of the dinuclear {mu}-sulfido molybdenum complex (Me{sub 2}NCH{sub 2}CH{sub 2} CpMo({mu}-S)){sub 2}S{sub 2}-CH{sub 2}, 4, and related derivatives. Complex 4 has been isolated and characterized by spectroscopic methods as well as by an X-ray diffraction study. The structure confirms a bis({mu}-sulfido) derivative in which the dimethylamino substituents of the Cp ligands are directed away from the Mo{sub 2}S{sub 4} core. Protonation of 4 produces the dicationic complex with dimethylammonium substituents, which is soluble in water and other polar solvents. Reaction of 4 with [CuOTf]{sub 2}{center_dot}C{sub 6} leads to the formation of a copper adduct [(Me{sub 2}NCH{sub 2}CH{sub 2} CpMo({mu}-S)){sub 2}Cu(S{sub 2}CH{sub 2})]OTF, 6a. NMR studies of 6a in CD{sub 2}Cl{sub 2} suggest that the copper ion is stabilized by two sulfido ligands and by weakly coordinated dimethylamino groups. 26 refs., 2 figs., 2 tabs.
