| Abstract: | The emission spectra of a series of molybdenum(II) chloride clusters containing thiolate ligands, Mo6(μ3-Cl)8(SR)6]2− (R = Et, Bu, Ph, Bn), have been recorded. These complexes all show a broad emission at ~700 nm after excitation at 337, 400
and 410 nm. Determination of the excited state lifetimes and quantum yields of these complexes in acetonitrile reveals that
(Bu4N)2Mo6(μ3-Cl)8(SPh)6] displays the longest excited state lifetime of this series (26 μs at 296 K).
