Tribarium pentastannide Chemical Properties,Usage,Production

Description

Tribarium pentastannide, Ba3Sn5, is a binary Zintl phase, not found in the phase diagram presented above. Sr3Sn5 and Ba3Sn5 were synthesized and structurally characterized. All compounds are isotypic and crystallize with a modified Pu3Pd5 structure type. The anionic substructure is composed of Sn₅^6- square pyramidal clusters, which are described as arachno clusters according to the Wade–Mingos electron counting rules. The electronic structure of the pyramidal Zintl anions and the influence of the number of skeletal electrons of these clusters were investigated using the ELF.
