Y Ta Pt Pt
YTaPt2 crystallizes in the triclinic P1 space group. Y(1) is bonded in a 2-coordinate geometry to two equivalent Ta(1), one Pt(1), and one Pt(2) atom. There is one shorter (3.45 Å) and one longer (3.63 Å) Y(1)-Ta(1) bond length. The Y(1)-Pt(1) bond length is 1.93 Å. The Y(1)-Pt(2) bond length is 1.07 Å. Ta(1) is bonded in a 8-coordinate geometry to two equivalent Y(1), four equivalent Ta(1), one Pt(1), and one Pt(2) atom. There are two shorter (2.96 Å) and two longer (3.66 Å) Ta(1)-Ta(1) bond lengths. The Ta(1)-Pt(1) bond length is 3.63 Å. The Ta(1)-Pt(2) bond length is 3.59 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a distorted bent 120 degrees geometry to one Y(1), one Ta(1), and one Pt(2) atom. The Pt(1)-Pt(2) bond length is 0.43 Å. In the second Pt site, Pt(2) is bonded in a bent 120 degrees geometry to one Y(1), one Ta(1), and one Pt(1) atom.
