SrCu2In crystallizes in the triclinic P1 space group. Sr(1) is bonded in a 6-coordinate geometry to two equivalent Cu(1), two equivalent Cu(2), and two equivalent In(1) atoms. There is one shorter (2.15 Å) and one longer (3.48 Å) Sr(1)-Cu(1) bond length. There is one shorter (1.99 Å) and one longer (3.41 Å) Sr(1)-Cu(2) bond length. There is one shorter (2.15 Å) and one longer (3.48 Å) Sr(1)-In(1) bond length. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 1-coordinate geometry to two equivalent Sr(1) and one Cu(2) atom. The Cu(1)-Cu(2) bond length is 1.03 Å. In the second Cu site, Cu(2) is bonded in a 3-coordinate geometry to two equivalent Sr(1), one Cu(1), and one In(1) atom. The Cu(2)-In(1) bond length is 1.03 Å. In(1) is bonded in a distorted single-bond geometry to two equivalent Sr(1) and one Cu(2) atom.
