TaVPt2 crystallizes in the monoclinic Pm space group. The structure is zero-dimensional and consists of one TaVPt2 cluster. Ta(1) is bonded in a single-bond geometry to one V(1), one Pt(1), and one Pt(2) atom. The Ta(1)-V(1) bond length is 0.58 Å. The Ta(1)-Pt(1) bond length is 1.20 Å. The Ta(1)-Pt(2) bond length is 0.11 Å. V(1) is bonded in a 2-coordinate geometry to one Ta(1) and one Pt(2) atom. The V(1)-Pt(2) bond length is 0.62 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 2-coordinate geometry to one Ta(1) and one Pt(2) atom. The Pt(1)-Pt(2) bond length is 1.16 Å. In the second Pt site, Pt(2) is bonded in a single-bond geometry to one Ta(1), one V(1), and one Pt(1) atom.
