Description Ferrocenyl diphosphine containing ironepalladium clusters [(CO)(6)Fe-2(mu(3)-Y)(2)Pd{PPh2(eta(5)-C5H4)Fe(eta(5)-C5H4) PPh2})] (Y = Se(9); Y = Te (10)) have been prepared by the room temperature reaction of [(CO)(6)Fe-2(mu(3)-Y)(2)Pd(PPh3)(2)] (Y = Se(5), Te(6)) with dppf. Structural characterization reveals an unusual chelating coordination by ferrocenyl diphosphine ligand attached to palladium atom. Room temperature reactions of dppe with metal clusters [Fe-3(mu(3)-Te)(2)(CO)(9)] (1), [Fe-3(mu(3)-Te)(2)(CO)(8)PPh3] (2) and [(CO)(6)Fe-2(mu(3)-Y) Pd-2(PPh3)(2)] (Y = Se(5), Te(6)) have been performed to obtain chalcogenide metal clusters [(CO)(18)Fe-6(mu(3)-Te)(4){mu-PPh2(CH2)(2)PPh2}] (3), [Fe-3(mu(3)-Te)(2)(CO)(8){PPh2(CH2)(2)PPh2}] (4) and [(CO)(6)Fe-2(mu(3)-Y) 2Pd{PPh2(CH2)(2)PPh2}] (Y = Se(7); Y = Te (8)) respectively. In all the compounds the diphosphine ligands are attached to metal centres by forming either chelating or bridging mode. The structures of compounds 3, 4, 7 and 9 have been established by single crystal X-ray crystallography. (C) 2011 Elsevier B. V. All rights reserved.
