英文摘要 | Crnsi15-n- (n = 1-3) clusters were investigated by using size-selected anion photoelectron spectroscopy combined with density functional theory calculations. the results show that the most stable structure of crsi14- is of c-2v symmetry with the cr atom encapsulated in a si-14 cage which can be viewed as a boat-shaped si-10 unit capped by four additional silicon atoms. a large homo-lumo gap of neutral crsi14 is confirmed based on the photo-electron spectrum of crsi14- anion. cr2si13- has two isomers nearly degenerate in energy: one can be characterized as one si atom interacting with a cr2si12 hexagonal prism while the other can be viewed as one si atom capping a distorted cr2si12 hexagonal antiprism. cr3si12- has a d-6d symmetric wheel structure in which three cr atoms form an axle surrounded by 12 si atoms. the magnetic moments of crsi14-, cr2si13-, and cr3si12- increase from 1 to 3 mu b and then to 7 mu b with the increasing number of cr atoms in the clusters. the magnetic moments of cr2si13- and cr3si12- are mainly contributed by the surface cr atoms. |
