Ta Ta Zn Sn
TaZnTaSn is BCT5 structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one TaSn cluster and one TaZn cluster. In the TaSn cluster, Ta(1) is bonded in a single-bond geometry to one Sn(1) atom. The Ta(1)-Sn(1) bond length is 0.80 Å. Sn(1) is bonded in a single-bond geometry to one Ta(1) atom. In the TaZn cluster, Ta(2) is bonded in a distorted single-bond geometry to one Zn(1) atom. The Ta(2)-Zn(1) bond length is 0.76 Å. Zn(1) is bonded in a single-bond geometry to one Ta(2) atom.
