Abstract: Photolysis of a benzene solution containing [Fe-3(CO)(9)(mu(3)-E)(2)] (E = S, Se), [(eta(5)-C5R5)Fe(CO)(2)(Cequivalent toCR(1))] (R = H, Me; R-1 = Ph, Fc), H2O and Et3N results in formation of new metal clusters [(eta(5)-C5R5)Fe-3(CO)(6)(mu(3)-E)(mu(3)-ECCH2R1)] (R = H, R-1 = Ph, E = S 1 or Se 2; R = Me, R-1 = Ph, E = S 3 or Se 4; R = H, R-1 = Fc, E = S 5; R = Me, R-1 = Fc, E = S 6 or Se 7). Reaction of [Fe-3(CO)(9)(mu(3)-S)(2)] with [(eta(5)-C5R5)Mo(CO)(3)(Cequivalent toCPh)] (R=H, Me), under same conditions, produces mixed-metal clusters [(eta(5)-C5R5)Mo-Fe-2(CO)(6)(mu(3)-S)(mu-SCCH2Ph)] (R = H 8; R = Me 9). Compounds 1-9 have been characterised by IR and H-1 and C-13-NMR spectroscopy. Structures of 1, 5 and 9 have been established crystallographically. A common feature in all these products is the formation of new C-chalcogen bond to give rise to a (ECCH2R1) ligand. (C) 2002 .
