金属甲酸根阴离子M（CO2）−，M = Ni、Pd和Pt，由电子诱导的CO2活化形成。它们是由激光蒸发产生的，其特征在于由质谱，阴离子光电子能谱和理论计算相结合。虽然中性过渡金属原子通常不能活化CO2，但向这些系统中添加过量电子导致形成化学吸附的阴离子络合物。这些是共价结合的甲酸盐样阴离子，其中它们的CO2部分显著减少。此外，我们还发现了中性Pd原子和CO2之间意外吸引力相互作用的证据。
The metallo-formate anions, M(CO2)−, M = Ni, Pd, and Pt, were formed by electron-induced CO2 activation. They were generated by laser vaporization and characterized by a combination of mass spectrometry, anion photoelectron spectroscopy, and theoretical calculations. While neutral transition metal atoms are normally unable to activate CO2, the addition of an excess electron to these systems led to the formation of chemisorbed anionic complexes. These are covalently bound, formate-like anions, in which their CO2 moieties are significantly reduced. In addition, we also found evidence for an unexpectedly attractive interaction between neutral Pd atoms and CO2.
