Ag2SnSi is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Ag2SnSi cluster. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 2-coordinate geometry to one Ag(2) and one Sn(1) atom. The Ag(1)-Ag(2) bond length is 1.30 Å. The Ag(1)-Sn(1) bond length is 1.30 Å. In the second Ag site, Ag(2) is bonded in a distorted single-bond geometry to one Ag(1) and one Si(1) atom. The Ag(2)-Si(1) bond length is 0.58 Å. Sn(1) is bonded in a distorted single-bond geometry to one Ag(1) and one Si(1) atom. The Sn(1)-Si(1) bond length is 0.58 Å. Si(1) is bonded in an L-shaped geometry to one Ag(2) and one Sn(1) atom.
