AgSi2P crystallizes in the triclinic P1 space group. Ag(1) is bonded in a distorted bent 120 degrees geometry to one Si(1), one Si(2), and one P(1) atom. The Ag(1)-Si(1) bond length is 1.31 Å. The Ag(1)-Si(2) bond length is 2.44 Å. The Ag(1)-P(1) bond length is 1.90 Å. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 2-coordinate geometry to one Ag(1), one Si(2), and one P(1) atom. The Si(1)-Si(2) bond length is 2.28 Å. The Si(1)-P(1) bond length is 2.33 Å. In the second Si site, Si(2) is bonded in a 5-coordinate geometry to one Ag(1), one Si(1), two equivalent Si(2), and one P(1) atom. Both Si(2)-Si(2) bond lengths are 2.67 Å. The Si(2)-P(1) bond length is 2.39 Å. P(1) is bonded in a 3-coordinate geometry to one Ag(1), one Si(1), and one Si(2) atom.
