In Cu Ag Ag
Ag2CuIn crystallizes in the triclinic P1 space group. 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 two equivalent In(1) atoms. The Ag(1)-Ag(2) bond length is 1.48 Å. There is one shorter (1.92 Å) and one longer (2.89 Å) Ag(1)-In(1) bond length. In the second Ag site, Ag(2) is bonded in a 4-coordinate geometry to one Ag(1), two equivalent Cu(1), and one In(1) atom. There is one shorter (1.60 Å) and one longer (2.36 Å) Ag(2)-Cu(1) bond length. The Ag(2)-In(1) bond length is 2.03 Å. Cu(1) is bonded in a 3-coordinate geometry to two equivalent Ag(2) and one In(1) atom. The Cu(1)-In(1) bond length is 2.22 Å. In(1) is bonded in a 4-coordinate geometry to one Ag(2), two equivalent Ag(1), and one Cu(1) atom.
