SmVW2 crystallizes in the trigonal R3m space group. Sm(1) is bonded in a 11-coordinate geometry to four equivalent V(1), three equivalent W(1), and four equivalent W(2) atoms. There are three shorter (2.75 Å) and one longer (3.17 Å) Sm(1)-V(1) bond length. All Sm(1)-W(1) bond lengths are 2.70 Å. There are three shorter (2.70 Å) and one longer (4.09 Å) Sm(1)-W(2) bond length. V(1) is bonded in a single-bond geometry to four equivalent Sm(1), one W(1), and three equivalent W(2) atoms. The V(1)-W(1) bond length is 0.92 Å. All V(1)-W(2) bond lengths are 2.70 Å. There are two inequivalent W sites. In the first W site, W(1) is bonded in a single-bond geometry to three equivalent Sm(1) and one V(1) atom. In the second W site, W(2) is bonded in a 6-coordinate geometry to four equivalent Sm(1) and three equivalent V(1) atoms.
