  • This is our prototype for the ternary form of the Co$_{2}$Si ($C7$) structure. See that page for similar binary compounds.
  • MnCuP and laudite (CuAsS) have the same AFLOW label, ABC_oP12_62_c_c_c. The structures are generated by the same symmetry operations with different sets of parameters (--params) specified in their corresponding CIF files.
  • The ICSD lists this structure under the prototype TiNiSi#MgSrSi.
