Be2SnCl is Copper structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Be2SnCl clusters. Be(1) is bonded in a distorted L-shaped geometry to one Sn(1) and one Cl(1) atom. The Be(1)-Sn(1) bond length is 0.83 Å. The Be(1)-Cl(1) bond length is 1.60 Å. Sn(1) is bonded in an L-shaped geometry to two equivalent Be(1) atoms. Cl(1) is bonded in a 2-coordinate geometry to two equivalent Be(1) atoms.
