InSn2 crystallizes in the triclinic P1 space group. There are two inequivalent In sites. In the first In site, In(1) is bonded in a single-bond geometry to one Sn(2) and one Sn(3) atom. The In(1)-Sn(2) bond length is 3.02 Å. The In(1)-Sn(3) bond length is 0.30 Å. In the second In site, In(2) is bonded in a 2-coordinate geometry to one Sn(3) and one Sn(4) atom. The In(2)-Sn(3) bond length is 2.97 Å. The In(2)-Sn(4) bond length is 2.98 Å. There are four inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 2-coordinate geometry to one Sn(2) and one Sn(4) atom. The Sn(1)-Sn(2) bond length is 2.40 Å. The Sn(1)-Sn(4) bond length is 1.86 Å. In the second Sn site, Sn(2) is bonded in a 5-coordinate geometry to one In(1), one Sn(1), one Sn(4), and two equivalent Sn(2) atoms. The Sn(2)-Sn(4) bond length is 3.18 Å. Both Sn(2)-Sn(2) bond lengths are 3.36 Å. In the third Sn site, Sn(3) is bonded in a single-bond geometry to one In(1) and one In(2) atom. In the fourth Sn site, Sn(4) is bonded in a 2-coordinate geometry to one In(2), one Sn(1), and one Sn(2) atom.
