Searching for Superconductivity in the Z = 12.67 Family
  The Z = 12.67 family of materials includes CaBeSi and NaAlSi which have been reported as non-superconducting and superconducting respectively. We show with an algorithm how to generate other members of this family. We discover through the material specific characterization dataset (MSCD) scheme and the symmetry conditions for superconductivity, why some are superconducting and others may not be superconducting.We estimate too the Tcs of members of this interesting family of materials.
