The structure described by AgSi3 crystallizes in the triclinic P-1 space group. Ag(1) is bonded in a 10-coordinate geometry to one Ag(1), three equivalent Si(1), three equivalent Si(2), and three equivalent Si(3) atoms. There are three inequivalent Si sites. In the first Si site, Si(1) is bonded in a 7-coordinate geometry to three equivalent Ag(1), two equivalent Si(2), and two equivalent Si(3) atoms. In the second Si site, Si(2) is bonded in a 7-coordinate geometry to three equivalent Ag(1), two equivalent Si(1), and two equivalent Si(3) atoms. In the third Si site, Si(3) is bonded in a 7-coordinate geometry to three equivalent Ag(1), two equivalent Si(1), and two equivalent Si(2) atoms. is represented by the CIF file [CIF]
