Jena, Puru Kandalam, Anil K. 2015-05-13T07:22:06Z Eichhorn, Bryan W. Zhang, Xinxing Through a synergetic combination of anion photoelectron spectroscopy and density functional theory based calculations, we have investigated the extent to which the aluminum moieties within selected magnesium-aluminum clusters are Zintl anions. Magnesium-aluminum cluster anions were generated in a pulsed arc discharge source. After mass selection, photoelectron spectra of Mg<sub>m</sub>Al<sub>n</sub> <sup>-</sup> (m, n = 1,6; 2,5; 2,12; and 3,11) were measured by a magnetic bottle, electron energy analyzer. Calculations on these four stoichiometries provided geometric structures and full charge analyses for the cluster anions and their neutral cluster counterparts, as well as photodetachment transition energies (stick spectra). Calculations revealed that, unlike the cases of recently reported sodium-aluminum clusters, the formation of aluminum Zintl anion moieties within magnesium-aluminum clusters was limited in most cases by weak charge transfer between the magnesium atoms and their aluminum cluster moieties. Only in cases of high magnesium content, e.g., in Mg<sub>3</sub>Al<sub>11</sub> and Mg<sub>2</sub>Al<sub>12</sub> <sup>-</sup>, did the aluminum moieties exhibit Zintl anion-like characteristics.
