| Abstract: | Re(CO)6]BF4] reacts with HMPA to form Re(CO)3(HMPA)3]BF4] (4), whose structure was determined by X-ray crystallography and proves to be a key intermediate in the ligand exchange reaction between three CO and Cp; and may be related to other cations such as Re(CO)3(H2O)3]+, Re(CO)3(CH3CN)3]+, Re(CO)3(DMSO)3]+, obtained by different ways, and important in the field of organometallic radiopharmaceuticals. |
