Gas phase reactions between PtH n − cluster anions and CO 2 were investigated by mass spectrometry, anion photoelectron spectroscopy, and computations. Two major products, PtCO 2 H − and PtCO 2 H 3 − , were observed. The atomic connectivity in PtCO 2 H − can be depicted as HPtCO 2 − , where the platinum atom is bonded to a bent CO 2 moiety on one side and a hydrogen atom on the other. The atomic connectivity of PtCO 2 H 3 − can be described as H 2 Pt(HCO 2 ) − , where the platinum atom is bound to a formate moiety on one side and two hydrogen atoms on the other. Computational studies of the reaction pathway revealed that the hydrogenation of CO 2 by PtH 3 − is highly energetically favorable.
