The structure described by LaAgSi is hexagonal omega structure-derived structured and crystallizes in the hexagonal P-6m2 space group. La(1) is bonded to six equivalent Ag(1) and six equivalent Si(1) atoms to form a mixture of edge and face-sharing LaSi6Ag6 cuboctahedra. Ag(1) is bonded in a 9-coordinate geometry to six equivalent La(1) and three equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to six equivalent La(1) and three equivalent Ag(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
