Se Br Cl Cl
SeBrCl2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one SeBrCl2 cluster. Se(1) is bonded in a distorted single-bond geometry to one Br(1) and one Cl(2) atom. The Se(1)-Br(1) bond length is 0.60 Å. The Se(1)-Cl(2) bond length is 0.47 Å. Br(1) is bonded in a 3-coordinate geometry to one Se(1), one Cl(1), and one Cl(2) atom. The Br(1)-Cl(1) bond length is 0.47 Å. The Br(1)-Cl(2) bond length is 0.53 Å. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted single-bond geometry to one Br(1) atom. In the second Cl site, Cl(2) is bonded in a single-bond geometry to one Se(1) and one Br(1) atom.
