Using Fe2(CO)6(mu-STe) and Fe3(CO)9(mu-3-S)(mu-3-Te) for the addition of coordinatively unsaturated species, the following new mixed metal, mixed chalcogen compounds have been obtained: Fe2(CO)6(mu-3-S)(mu-3-Te)M(PPh3)2 (M = Pt, Pd), Fe2Ru(CO)9(mu-3-S)(mu-3-Te) and Fe4-xRux(CO)11(mu-4-S)(mu-4-Te) (x = 0-2). The formation of the triphenylphosphine derivatives, Fe3(CO)9-x(PPh3)x(mu-3-S)(mu-3-Te) (x = 1, 2) and Fe3(CO)9(PPh3)(mu-3-S)(mu-3-Te) are also reported.
