Abstract
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 cha lcogenide 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.
