Abstract: | Thermal and photochemical interconversion occurs between the isomeric pair of tetrathiotungstate WS4]2− clusters 1 and 2 , which were formed by thermolysis of Cp*2Ru2S4] and W(CO)3(MeCN)3] Eq. (1)] and then structurally characterized. During synthesis, a dramatic redistribution of ligands between the Ru and W atoms takes place without the loss of any CO and S ligands. |
