Ta Pt Rh Rh
TaRh2Pt crystallizes in the triclinic P1 space group. Ta(1) is bonded in a 1-coordinate geometry to one Rh(2), two equivalent Rh(1), and one Pt(1) atom. The Ta(1)-Rh(2) bond length is 3.14 Å. There is one shorter (2.03 Å) and one longer (2.09 Å) Ta(1)-Rh(1) bond length. The Ta(1)-Pt(1) bond length is 1.34 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 4-coordinate geometry to two equivalent Ta(1), one Rh(2), and one Pt(1) atom. The Rh(1)-Rh(2) bond length is 1.83 Å. The Rh(1)-Pt(1) bond length is 1.95 Å. In the second Rh site, Rh(2) is bonded in a 3-coordinate geometry to one Ta(1), one Rh(1), and one Pt(1) atom. The Rh(2)-Pt(1) bond length is 1.91 Å. Pt(1) is bonded in a single-bond geometry to one Ta(1), one Rh(1), and one Rh(2) atom.
