英文摘要ASi(n)(-) (A = B and Al; n = 1-6) binary cluster anions were generated by laser ablation of samples composed of mixtures of Si and A (A = B and Al), and studied in the gas phase by tandem time-of-flight mass spectrometry. Some abundant ions are present in the mass spectrum, indicating that the clusters with these ions have stable structures. The structures of ASi(n)(-) clusters were investigated theoretically by the density functional theory (DFT) method and the energetically lowest-lying structures were obtained. The binary clusters BSin- and AlSin-, with the same number of n, share different geometric structures except for ASi(n)(-) with n =1 and 6, which have the same geometric structures in the ground state. For all the anionic clusters ASi(n)(-), the lower spin state is lower in energy than the higher spin state in their optimized structures except for the linear ASi(-) anions, for which the triplet state is lower in energy than the singlet. Calculations of the bonding energy (BE), energy gain (Delta) and HOMO-LUMO energy gaps confirm that the cluster ASi(5)(-) has a very stable structure, which agrees well with the experimental results.
