VPt4Ag crystallizes in the trigonal R3m space group. V(1) is bonded to three equivalent Pt(1), three equivalent Pt(2), and one Ag(1) atom to form distorted corner-sharing VAgPt6 tetrahedra. All V(1)-Pt(1) bond lengths are 2.67 Å. All V(1)-Pt(2) bond lengths are 3.07 Å. The V(1)-Ag(1) bond length is 1.93 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(2) is bonded in a 9-coordinate geometry to three equivalent V(1), three equivalent Pt(1), and three equivalent Ag(1) atoms. All Pt(2)-Pt(1) bond lengths are 1.35 Å. All Pt(2)-Ag(1) bond lengths are 3.32 Å. In the second Pt site, Pt(1) is bonded in a 5-coordinate geometry to one V(1), one Pt(2), two equivalent Pt(1), and one Ag(1) atom. Both Pt(1)-Pt(1) bond lengths are 0.78 Å. The Pt(1)-Ag(1) bond length is 1.67 Å. Ag(1) is bonded in a 4-coordinate geometry to one V(1), three equivalent Pt(1), and three equivalent Pt(2) atoms.
