WCr2Sn is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one WCr2Sn cluster. W(1) is bonded in a 3-coordinate geometry to one Cr(1), one Cr(2), and one Sn(1) atom. The W(1)-Cr(1) bond length is 1.32 Å. The W(1)-Cr(2) bond length is 0.65 Å. The W(1)-Sn(1) bond length is 0.55 Å. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a distorted single-bond geometry to one W(1) atom. In the second Cr site, Cr(2) is bonded in a 2-coordinate geometry to one W(1) and one Sn(1) atom. The Cr(2)-Sn(1) bond length is 0.55 Å. Sn(1) is bonded in a 2-coordinate geometry to one W(1) and one Cr(2) atom.
