Iron cyclopentadienyl(triphenylphosphine)carbonylphenyl telluride adducts with manganese, tungsten, and rhodium complexes

The reactions of CpFe(CO)(PPh3)TePh (I) with CpMn(CO)2(THF), W(CO)5(THF), and [Cp*RhCl2]2 gave heterometallic adducts CpFe(CO)(PPh3)(µ-TePh)CpMn(CO)2 (II), CpFe(CO)(PPh3)(µ-TePh)W(CO)5 (III), and CpFe(CO)(PPh3)(µ-TePh)RhCl2Cp* (IV). The structures of II, III, and IV · 3CDCl3 (CIF files CCDC nos. 063654, 1063655, 1038123) were studied by X-ray diffraction. In all complexes, metal atoms are connected by only one tellurophenyl bridge. All M → Te bonds are substantially shortened with respect to the sum of the covalent radii owing to the additional M → Te dative interactions.
