Unexpected diastereoisomeric-trimers in the crystalline structure of triflatetriphenylphosphinesilver(I)
摘要:
The synthesis and spectroscopic properties of [Ag-3(O3SCF3)(3)(PR3)(3)] (PR3 = PPh3 and PPh2Me) are described and the trimeric nature has been confirmed in the case of the PPh3 derivative. The X-ray crystal structure of [Ag-3(O3SCF3)(3)(PPh3)(3)] shows that each triflate group is in a different coordination mode and that there are two diastereoisomers in the asymmetric unit.
