Abstract
CaLi2, a member of the Z =8.67 family, with Ne =1.333 is superconducting at 14K at 40 GPA pressure. Through computational combinatorial synthesis of the Z =4.67 and Z=12.67 families, we create new members of the Z =8.67 family. We discover over 160 potential members of the Z = 8.67 family with Ne=2.67 that have more than three elements. Our estimations suggest that most of them will be superconducting with Tcs between 30K and 60K at ambient pressure.
