质谱和光电子能谱以及第一原理理论计算已经被用于研究以下钠-锡簇阴离子/中性簇组合(Na(n)Sn(4))(-)/(Na(n)Sn(4)),n = 0-4和(NaSn(m))(-)/(NaSn(m)),m = 4-7)的电子和几何性质。这些协同作用的研究发现,特定的Zintl阴离子,这是已知的发生在凝聚Zintl相,也存在作为自由集群内的稳定部分。特别地,簇阴离子(Na(3)Sn(4))(-)是非常稳定的,并且被表征为(Na(+))(3)(Sn(4))(-4);其部分(Sn(4))(-4)是Zintl阴离子的经典实例。此外,簇阴离子(NaSn(5))(-)是在我们的质谱中观察到的最丰富的种类,并且其被表征为Na(+)(Sn(5))(2-)。其部分(Sn(5))(2-)也已知作为Zintl阴离子存在于凝聚相中。
Mass spectrometry and photoelectron spectroscopy together with first principles theoretical calculations have been used to study the electronic and geometric properties of the following sodium-tin, cluster anion/neutral cluster combinations, (Na(n)Sn(4))(-)/(Na(n)Sn(4)), n = 0-4 and (NaSn(m))(-)/(NaSn(m)), m = 4-7. These synergistic studies found that specific Zintl anions, which are known to occur in condensed Zintl phases, also exist as stable moieties within free clusters. In particular, the cluster anion, (Na(3)Sn(4))(-) is very stable and is characterized as (Na(+))(3)(Sn(4))(-4); its moiety, (Sn(4))(-4) is a classic example of a Zintl anion. In addition, the cluster anion, (NaSn(5))(-) was the most abundant species to be observed in our mass spectrum, and it is characterized as Na(+)(Sn(5))(2-). Its moiety, (Sn(5))(2-) is also known to be present as a Zintl anion in condensed phases.
