- 中文摘要: The title compounds, Mo(CO)/sub 2/(Ph/sub 2/PCH/sub 2/PPh/sub 2/)(Ph/sub 2/PCH/sub 2/CH/sub 2/PPh/sub 2/), Mo(CO)/sub 2/(dppm)(dppe) 1, and Mo(CO)/sub 2/(Ph/sub 2/PCH/sub 2/CH/sub 2/PPh/sub 2/)(Ph/sub 2/PCH=CHPPh/sub 2/), Mo(CO)/sub 2/(dppe)(cis-vpp) 2, were prepared from Mo(CO)/sub 6/ and the corresponding bidentate diphosphine ligands in n-decane under nitrogen atmosphere. Crystals of 1 are monoclinic, space group P2/sub 1//c, with a=19.072(3), b=11.348(3), c=23.57(1).ANG.,.beta.=99.64(3). degree., Z=4, and the final residual R(F)=0.044 for 4810 observed reflections; data of 2 are triclinic, space group P1, with a=12.091(3), b=12.186(8), c=18.934(5).ANG., .alpha.=96.93(4), .beta.=108.15(2),.gamma.=107.08(4).degree., Z=2, and the final residual R(F)=0.058 for 4570 observed reflections. The distortion of compound 1 is more pronounced than that of compound 2. The two Mo-P lengths in the same bidentate chelate ligand for both compounds are different. Among them, the two larger Mo-P bond lengths for compound 2 are similar, but significantly different for 1.
