Sc Se Se Cl
ScSeSeCl is alpha carbon monoxide-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ScSe clusters and two SeCl clusters. In each ScSe cluster, Sc(1) is bonded in a single-bond geometry to one Se(2) atom. The Sc(1)-Se(2) bond length is 0.62 Å. Se(2) is bonded in a single-bond geometry to one Sc(1) atom. In each SeCl cluster, Se(1) is bonded in a single-bond geometry to one Cl(1) atom. The Se(1)-Cl(1) bond length is 0.25 Å. Cl(1) is bonded in a single-bond geometry to one Se(1) atom.
