Treatment of Ru 3(CO) 12 with Ph 3PS affords the compounds [Ru 3(μ 3-S) 2(CO) 9 - n(PPh 3) n] (n = 1 (1a), 2 (2a)) and [Ru 3(μ 3-S)(μ 3-CO)(CO) 7(PPh 3) 2] (3a) as the major products. Single crystal X-ray diffraction studies of [Ru 3(μ 3-S) 2(CO) 8(PPh 3)] and [Ru 3(μ 3-S) (μ 3-CO)(CO) 7(PPh 3) 2] show these two classes of compounds to contain square pyramidal Ru 3S 2 and trigonal pyramidal Ru 3S metal cores, respectively, with the latter being isostructural to the analogous selenide cluster compound. The clusters [Ru 3(μ 3-E) 2(CO) 9 - n(PPh 3) n] (E = S, n = 1; E = Se, n = 2) readily undergo ligand displacement reactions with PPh 3 to afford the compounds [Ru 3(μ 3-E) 2(CO) 6(PPh 3) 3] (E = S, 5a; E = Se 5b). The mixed chalcogenide cluster, [Ru 3(μ 3-S)(μ 3-Se) (CO) 7(PPh 3) 2] (6), was prepared from the reaction of [Ru 3(μ 3-S)(μ 3-CO)(CO) 7(PPh 3) 2] and SePPh 3. The optical limiting properties of the complexes 1a,b, 2a,b, 5a,b have been measured by the Z-scan technique employing 40 ns pulses at 523 nm; power limiting was observed for all clusters under our experimental conditions. © 2005 Elsevier B.V.
