AgIn crystallizes in the trigonal R3 space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted single-bond geometry to one In(1) and two equivalent In(2) atoms. The Ag(1)-In(1) bond length is 1.44 Å. There is one shorter (2.80 Å) and one longer (3.20 Å) Ag(1)-In(2) bond length. In the second Ag site, Ag(2) is bonded in a trigonal non-coplanar geometry to one In(2) and three equivalent In(1) atoms. The Ag(2)-In(2) bond length is 3.07 Å. All Ag(2)-In(1) bond lengths are 1.25 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded in a distorted bent 120 degrees geometry to one Ag(1) and one Ag(2) atom. In the second In site, In(2) is bonded in a 7-coordinate geometry to one Ag(2) and six equivalent Ag(1) atoms.
