Description Room temperature reactions of [Fe(3)Te(2)(CO)(8)(PPh(3))] (2) and [(CO)(6)Fe(2)PdY(2)(PPh(3))(2)] (Y = Se (6), Te (7)) with bis-(diphenylphosphino) methane (dppm) in dichloromethane solution led to the formation of a tellurium bridged cluster, [Fe(3)Te(2)(CO)(8)(mu-dppm)] (4) and mixed metal clusters, [(CO)(12)Fe(4)Y(4)Pd(2)(dppm)(2)] (Y = Se (8), Te (9)) respectively. In both the reactions, diphosphine incorporation has taken place by replacing one or two triphenylphosphine ligand. The structures of compounds 4, 6 and 9 were established crystallographically.
