Bromopentacarbonylrhenium(I)
Bromopentacarbonylrhenium(I) is a chemical compound with the formula Re(CO)5Br. This organometallic compound is a colorless liquid that is soluble in organic solvents. It is a member of the class of compounds known as metal carbonyls, which are complexes that contain a metal atom bonded to carbon monoxide ligands.
Structure and Bonding[edit | edit source]
Bromopentacarbonylrhenium(I) consists of a rhenium atom at the center, surrounded by five carbon monoxide ligands and one bromine atom. The rhenium atom is in the +1 oxidation state. The molecule has a distorted octahedral geometry, with the bromine atom occupying one of the axial positions.
Synthesis[edit | edit source]
Bromopentacarbonylrhenium(I) can be synthesized by the reaction of hexacarbonylrhenium with bromine. The reaction is typically carried out in a solvent such as dichloromethane.
Applications[edit | edit source]
Bromopentacarbonylrhenium(I) is used as a precursor to other rhenium complexes. It can also be used in the synthesis of radiopharmaceuticals due to the radioactive nature of some isotopes of rhenium.
Safety[edit | edit source]
Like many organometallic compounds, bromopentacarbonylrhenium(I) is sensitive to air and moisture. It should be handled under an inert atmosphere and stored in a cool, dry place.
