摘要：
Treatment of [Ru3(CO)10(μ-dppm)] (1) with the ditelluride Te2(C6H4OEt-4)2 in refluxing toluene afforded the new aryltellurol bridged complex [Ru2(CO)4(μ-TeC6H4OEt-4)2 (μ-dppm)] (2) together with three known complexes [Ru4(CO)8(μ-CO)(μ4-Te)2(μ-dppm)] (3), [Ru2(CO)6{μ-CH2PPh(C6H4)PPh}] (4), and [Ru2(CO)6{μ-C6H4PPh(CH2)PPh}] (5). All the four complexes were characterized by spectroscopic methods, including an X-ray structure determination for 5. Complex 5 crystallizes in the monoclinic space group P21/c with a = 13.650(2), b = 9.995(2), c = 18.929(3) Å, β = 97.49(2)°, V = 2560.4(8) Å3, and Z = 4. In this complex the two ruthenium atoms are bridged by the phosphino-phosphide ligand C6H4PPh(CH2)PPh which is attached to one Ru by the C6H4 group and a P atom while to the other Ru by both the two P atoms. Both the ruthenium atoms show distorted octahedral geometry. The Ru—Ru bond length is 2.8719(7) Å.
