VW4Pt crystallizes in the trigonal R3m space group. V(1) is bonded in a 7-coordinate geometry to one W(2) and six equivalent W(1) atoms. The V(1)-W(2) bond length is 3.09 Å. All V(1)-W(1) bond lengths are 2.82 Å. There are two inequivalent W sites. In the first W site, W(2) is bonded in a 4-coordinate geometry to one V(1), three equivalent W(1), and three equivalent Pt(1) atoms. All W(2)-W(1) bond lengths are 1.26 Å. All W(2)-Pt(1) bond lengths are 3.31 Å. In the second W site, W(1) is bonded in a 2-coordinate geometry to two equivalent V(1), one W(2), two equivalent W(1), and one Pt(1) atom. Both W(1)-W(1) bond lengths are 0.73 Å. The W(1)-Pt(1) bond length is 1.75 Å. Pt(1) is bonded in a 6-coordinate geometry to three equivalent W(1) and three equivalent W(2) atoms.
