The compound described by AgSi3 crystallizes in the hexagonal P6_3/mmc space group. Ag(1) is bonded to twelve equivalent Si(1) atoms to form a mixture of face and corner-sharing AgSi12 cuboctahedra. Si(1) is bonded in a 10-coordinate geometry to four equivalent Ag(1) and six equivalent Si(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
