SrV2Zn is Heusler structured and crystallizes in the trigonal R3m space group. Sr(1) is bonded in a 11-coordinate geometry to four equivalent V(1), four equivalent V(2), and three equivalent Zn(1) atoms. There are three shorter (2.92 Å) and one longer (3.26 Å) Sr(1)-V(1) bond length. There are three shorter (2.92 Å) and one longer (3.26 Å) Sr(1)-V(2) bond length. All Sr(1)-Zn(1) bond lengths are 3.18 Å. There are two inequivalent V sites. In the first V site, V(1) is bonded in a 4-coordinate geometry to four equivalent Sr(1) atoms. In the second V site, V(2) is bonded in a 5-coordinate geometry to four equivalent Sr(1) and one Zn(1) atom. The V(2)-Zn(1) bond length is 2.20 Å. Zn(1) is bonded in a distorted single-bond geometry to three equivalent Sr(1) and one V(2) atom.
