Abstract: Thermolysis of a mixture of [(eta(5)-C5Me5)W(CO)(3)(CCPh)] and [Fe-3(CO)(9)(mu(3)-Se)(2)] in toluene solvent at 90 degrees C in air yields the unusual diselenaoxoacetylide compound [(eta(5)-C5Me5)W(O)(Se-2)(CCPh)] (1). When the same reaction is carried out under nitrogen atmosphere, the pentaselenaacetylide compound [eta(5)-C5Me5)W(Se-2)(Se3CCPh)] (2) and the previously reported cluster [(eta(5)-C5Me5)(2)W2Fe3(CO)(6)(mu(3)-Se)(2)(mu(4)-CC(Ph)C(Ph)C] (3) are formed. Structures of 1 and 2 have been established crystallographically.
