Resumo

Laser-ablated rhenium atoms react with CO2 molecules upon co-condensation in excess argon at 7 K and neon at 4 K. Besides neutral products [OReCO, O2ReCO, ORe(CO)2, and O2Re(CO)2], anionic species [OReCO-, ORe(CO)2-] are formed and identified through annealing, ultraviolet irradiation, isotopic substitution, and CCl4 doping experiments. DFT calculations have been performed on all product species, and the very good overall agreement between the calculated and the observed vibrational frequencies supports the product identifications.
