[Re(CO)3(bipy)(ClO4)]: Synthesis in a Proton-Donor Solvent, Crystal, and Molecular Structure

The complex [Re(CO)(3)(bipy)(ClO4)] (bipy = 2,2MODIFIER LETTER PRIME-bipyridine) was prepared by the reaction of [Re(CO)(3)(H2O,EtOH)(3)](ClO4) with bipy in aqueous ethanol, followed by crystallization from dichloromethane. The composition and structure of the complex were determined by single crystal X-ray diffraction analysis. The complex has a molecular octahedral structure with bidentate coordination of bipy and inner-sphere monodentate coordination of perchlorate ion in the fac-position to bipy. The complex was also characterized by IR and UV-visible absorption spectroscopy.
