Abstract:
Reactions of 1,2,3,4-tetraphenyl-1,2,3,4-tetraphospholane(Ⅰ) with triruthenium Dodecacarbonyl in 1:2 molar ratio at different temperatures resulted in the cleavage of P-P bonds in Ⅰ to afford three new isomeric heptnuclear ruthenium clusters containing phosphido and phosphinidene ligands with the formula of[Ru7(CO)15(μ4-PPh)2{(μ2-PPH)2CH2}]. All these new obtained clusters have been characterized by elementary analysis, IR, 1H, and 13P NMR spectroscopy methods, and their molecular structures have been established by single crystal X-ray diffraction analysis, Cluster 1 is a chiral molecule alnd two enantiomers (la,lb) are present in it, The structure of 1 is found to contain two square pyramids skeleton sharing a triangular face.
