ZnSeCl2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one ZnSeCl2 cluster. Zn(1) is bonded in a water-like geometry to one Se(1) and one Cl(2) atom. The Zn(1)-Se(1) bond length is 2.08 Å. The Zn(1)-Cl(2) bond length is 2.39 Å. Se(1) is bonded in a 2-coordinate geometry to one Zn(1) and one Cl(1) atom. The Se(1)-Cl(1) bond length is 1.21 Å. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted single-bond geometry to one Se(1) atom. In the second Cl site, Cl(2) is bonded in a single-bond geometry to one Zn(1) atom.
