Abstract

A nona-vacant Keggin-type tricarbonyl rhenium derivative [(NH₄)₅]{[PMo₃O₁₆][Re(CO)₃]₄}·1.5H₂O was obtained and characterized. Its frontier orbitals were computed by density functional theory (DFT) calculations. Furthermore, it could act as a Lewis acid catalyst and promote the conversion of CO₂ to cyclic carbonate under mild reaction conditions with pyrrolidinium bromide as a co-catalyst.
