The crystal structure described by CaAgBi is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6_3/mmc space group. Ca(1) is bonded to six equivalent Ag(1) and six equivalent Bi(1) atoms to form a mixture of edge and face-sharing CaAg6Bi6 cuboctahedra. Ag(1) is bonded in a 9-coordinate geometry to six equivalent Ca(1) and three equivalent Bi(1) atoms. Bi(1) is bonded in a 9-coordinate geometry to six equivalent Ca(1) and three equivalent Ag(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
