YSc2Cl crystallizes in the trigonal R3m space group. Y(1) is bonded in a 5-coordinate geometry to one Sc(1), one Sc(2), and three equivalent Cl(1) atoms. The Y(1)-Sc(1) bond length is 1.76 Å. The Y(1)-Sc(2) bond length is 1.76 Å. All Y(1)-Cl(1) bond lengths are 3.14 Å. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a distorted linear geometry to one Y(1) and one Cl(1) atom. The Sc(1)-Cl(1) bond length is 1.76 Å. In the second Sc site, Sc(2) is bonded in a single-bond geometry to one Y(1) atom. Cl(1) is bonded in a single-bond geometry to three equivalent Y(1) and one Sc(1) atom.
