ScZrMo is half-Heusler structured and crystallizes in the trigonal R3m space group. Sc(1) is bonded in a single-bond geometry to three equivalent Zr(1) and one Mo(1) atom. All Sc(1)-Zr(1) bond lengths are 2.70 Å. The Sc(1)-Mo(1) bond length is 1.79 Å. Zr(1) is bonded in a 7-coordinate geometry to three equivalent Sc(1) and four equivalent Mo(1) atoms. There is one shorter (2.53 Å) and three longer (2.89 Å) Zr(1)-Mo(1) bond lengths. Mo(1) is bonded in a 1-coordinate geometry to one Sc(1) and four equivalent Zr(1) atoms.
