- 中文摘要: The thermal reaction between the tris(.mu.-Hydrido)dodecacarbonyltrirhenium (o) cluster and triphenylphosphine or triphenylphosphite results in a trisubstituted rhenium cluster as the major product. The results of an X-ray structural analysis of H/sub 3/Re/sub 3/(CO)/sub 9/(PPh/sub 3/) are: Mr=1597.57, Monoclinic, P/sub 21//n, a=15.598(1), b=9.530(2), c= 41.685(3) A, .beta.=80.60(1)/sup .degree./, V=6113.(1) A/sup 3/, Z=4, D/sub c/=1.736g/cm/sup 3/, CuK/sub a/, .lambda.=1.54056A, .mu.=121.23cm/sup -1/, F(000)=3059.17, room temperature, R=0.049 for 7361 reflections with I.gtoreq.2.5.delta.(I). The molecule has a triangular Re/sub 3/ core coordinated propellerwise by three PPh/sub 3/ ligands in the molecular plane with virtual C/sub 3h/ symmetry.
