Zr10(IrPt)3 crystallizes in the hexagonal P-62m space group. There are three inequivalent Zr sites. In the first Zr site, Zr(1) is bonded in a 6-coordinate geometry to three equivalent Ir(1) and three equivalent Pt(1) atoms. In the second Zr site, Zr(2) is bonded in a 5-coordinate geometry to three equivalent Ir(1) and two equivalent Pt(1) atoms. In the third Zr site, Zr(3) is bonded in a 5-coordinate geometry to two equivalent Ir(1) and three equivalent Pt(1) atoms. Ir(1) is bonded in a 9-coordinate geometry to two equivalent Zr(3), three equivalent Zr(2), and four equivalent Zr(1) atoms. Pt(1) is bonded in a 9-coordinate geometry to two equivalent Zr(2), three equivalent Zr(3), and four equivalent Zr(1) atoms.
Zr10(IrPt)3 crystallizes in the hexagonal P-62m space group. There are three inequivalent Zr sites. In the first Zr site, Zr(1) is bonded in a 6-coordinate geometry to three equivalent Ir(1) and three equivalent Pt(1) atoms. All Zr(1)-Ir(1) bond lengths are 2.87 Å. All Zr(1)-Pt(1) bond lengths are 2.88 Å. In the second Zr site, Zr(2) is bonded in a 5-coordinate geometry to three equivalent Ir(1) and two equivalent Pt(1) atoms. There are two shorter (2.81 Å) and one longer (2.97 Å) Zr(2)-Ir(1) bond length. Both Zr(2)-Pt(1) bond lengths are 3.02 Å. In the third Zr site, Zr(3) is bonded in a 5-coordinate geometry to two equivalent Ir(1) and three equivalent Pt(1) atoms. Both Zr(3)-Ir(1) bond lengths are 3.00 Å. There are two shorter (2.82 Å) and one longer (2.94 Å) Zr(3)-Pt(1) bond length. Ir(1) is bonded in a 9-coordinate geometry to two equivalent Zr(3), three equivalent Zr(2), and four equivalent Zr(1) atoms. Pt(1) is bonded in a 9-coordinate geometry to two equivalent Zr(2), three equivalent Zr(3), and four equivalent Zr(1) atoms.
