ScCrSe is Hg_xSn structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one ScCrSe cluster. Sc(1) is bonded in a distorted single-bond geometry to one Se(1) atom. The Sc(1)-Se(1) bond length is 1.27 Å. Cr(1) is bonded in a single-bond geometry to one Se(1) atom. The Cr(1)-Se(1) bond length is 0.86 Å. Se(1) is bonded in a distorted bent 120 degrees geometry to one Sc(1) and one Cr(1) atom.
