Abstract
There are two high-temperature superconductor structures in the ScCaH<sub>2n</sub>(<italic>n</italic>= 1–6) system. Among them, ScCaH<sub>8</sub>contains H<sub>18</sub>-cages and the<italic>T</italic><sub>c</sub>reaches 212 K (200 GPa), while ScCaH<sub>12</sub>has H<sub>24</sub>-cages and the<italic>T</italic><sub>c</sub>reaches 182 K (200 GPa).
