Synthesis and characterisation of [Fe2M3(μ4-E)(μ3-E′)(CO)17] and [Os3(μ3-E)(μ3-E′)(CO)9] (M=Os or Ru; E=S, Se, Te; E′=Se, Te)
摘要:
A set of new chalcogen-bridged mixed metal clusters [Fe2Os3(mu(4)-E)(mu(3)-E')(CO)(17)] (2, EE' = SeTe; 3, EE' = STe; 4, EE' = Se-2; 5 EE' = SSe) and [Fe2Ru3(mu(4)-E)(mu(3)-E')(CO)(17)] (12, EE' = SeTe; 13, EE' = STe; 14, EE' = Se-2; 15, EE' = SSe) has been synthesised by facile methods. Thermolysis or photolysis of compounds 2, 3 and 5 afforded the new triosmium mixed chalcogenide clusters [Os-3(mu(3)-E)(mu(3)-E)(CO)(9)] (7, EE' = SeTe; 8, EE' = STe; 10, EE' = SSe). All new compounds were characterised by IR and H-1-, Se-77- and Te-125-NMR spectroscopy. Clusters 8, 9 and 12 were structurally characterised by single crystal X-ray diffraction methods.

or Os3(μ3-Se)cluster cores with three metal–metal bonds while 2, 7, 10, 11 and 12contain Os3(μ3-S)2or Os3(μ3-Se)2 cores two metal–metal bonds. The two hydroxy ligands in the triosmium cluster 6 bridging the open osmium-osmium edge and are probably derived from water. A study of the dynamic exchange of PPh3 ligands in 5 is also reported.

room temperature reactions of Ph3PSe with the triosmium clusters Os3(CO)11(CH3CN), Os3(CO)10(CH3CN)2 and Os3(μ-H)2(CO)10 have been investigated. The reaction with an equimolar amount of Os3(CO)11(CH3CN) afforded the known clusters Os3(μ3-Se)2(CO)9, 1, and Os3(CO)11(PPh3), 2, and the new cluster Os3(μ3-Se)(CO)9(PPh3), 3. The analogous reaction with Os3(CO)10(CH3CN)2 gave 1 and 2; reaction with 0.5 equivalent
