U V Sn Sn
UVSn2 is Heusler structured and crystallizes in the trigonal R3m space group. U(1) is bonded in a distorted body-centered cubic geometry to four equivalent Sn(1) and four equivalent Sn(2) atoms. There are three shorter (3.00 Å) and one longer (3.09 Å) U(1)-Sn(1) bond length. There are three shorter (3.00 Å) and one longer (3.09 Å) U(1)-Sn(2) bond length. V(1) is bonded in a distorted body-centered cubic geometry to four equivalent Sn(1) and four equivalent Sn(2) atoms. There are three shorter (3.00 Å) and one longer (3.09 Å) V(1)-Sn(1) bond length. There is one shorter (2.82 Å) and three longer (3.09 Å) V(1)-Sn(2) bond lengths. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a body-centered cubic geometry to four equivalent U(1) and four equivalent V(1) atoms. In the second Sn site, Sn(2) is bonded in a body-centered cubic geometry to four equivalent U(1) and four equivalent V(1) atoms.
