Cr2BSn is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Cr2BSn clusters. Cr(1) is bonded in a distorted single-bond geometry to one B(1) and one Sn(1) atom. The Cr(1)-B(1) bond length is 0.48 Å. The Cr(1)-Sn(1) bond length is 1.02 Å. B(1) is bonded in a distorted L-shaped geometry to two equivalent Cr(1) atoms. Sn(1) is bonded in a 2-coordinate geometry to two equivalent Cr(1) atoms.
