Ta Be Pt Pt
BeTaPt2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one BeTaPt2 cluster. Be(1) is bonded in a 1-coordinate geometry to one Ta(1) atom. The Be(1)-Ta(1) bond length is 0.80 Å. Ta(1) is bonded in a 1-coordinate geometry to one Be(1) and one Pt(1) atom. The Ta(1)-Pt(1) bond length is 2.19 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 1.11 Å. In the second Pt site, Pt(2) is bonded in a 1-coordinate geometry to one Pt(1) atom.
