The material structure described by PrAgSi is hexagonal omega structure-derived structured and crystallizes in the tetragonal I4_1md space group. Pr(1) is bonded to six equivalent Ag(1) and six equivalent Si(1) atoms to form a mixture of face and edge-sharing PrSi6Ag6 cuboctahedra. Ag(1) is bonded in a 9-coordinate geometry to six equivalent Pr(1) and three equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to six equivalent Pr(1) and three equivalent Ag(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
