Ir3Pt5 crystallizes in the triclinic P1 space group. There are six inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 7-coordinate geometry to one Ir(6), two equivalent Ir(4), one Pt(5), one Pt(6), and two equivalent Pt(1) atoms. The Ir(1)-Ir(6) bond length is 3.05 Å. There is one shorter (2.54 Å) and one longer (2.67 Å) Ir(1)-Ir(4) bond length. The Ir(1)-Pt(5) bond length is 3.29 Å. The Ir(1)-Pt(6) bond length is 3.24 Å. There is one shorter (3.16 Å) and one longer (3.27 Å) Ir(1)-Pt(1) bond length. In the second Ir site, Ir(2) is bonded in a single-bond geometry to one Ir(4), one Pt(10), and one Pt(3) atom. The Ir(2)-Ir(4) bond length is 1.99 Å. The Ir(2)-Pt(10) bond length is 2.19 Å. The Ir(2)-Pt(3) bond length is 0.29 Å. In the third Ir site, Ir(3) is bonded in a single-bond geometry to one Ir(6) and one Pt(9) atom. The Ir(3)-Ir(6) bond length is 1.60 Å. The Ir(3)-Pt(9) bond length is 0.56 Å. In the fourth Ir site, Ir(4) is bonded in a 5-coordinate geometry to one Ir(2), one Ir(5), two equivalent Ir(1), and one Pt(1) atom. The Ir(4)-Ir(5) bond length is 2.25 Å. The Ir(4)-Pt(1) bond length is 2.60 Å. In the fifth Ir site, Ir(5) is bonded in a single-bond geometry to one Ir(4) and one Pt(3) atom. The Ir(5)-Pt(3) bond length is 0.56 Å. In the sixth Ir site, Ir(6) is bonded in a distorted single-bond geometry to one Ir(1) and one Ir(3) atom. There are ten inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 4-coordinate geometry to one Ir(4), two equivalent Ir(1), one Pt(10), one Pt(5), and one Pt(6) atom. The Pt(1)-Pt(10) bond length is 1.54 Å. The Pt(1)-Pt(5) bond length is 1.74 Å. The Pt(1)-Pt(6) bond length is 1.74 Å. In the second Pt site, Pt(2) is bonded in a 3-coordinate geometry to one Pt(7), one Pt(8), and one Pt(9) atom. The Pt(2)-Pt(7) bond length is 1.71 Å. The Pt(2)-Pt(8) bond length is 1.60 Å. The Pt(2)-Pt(9) bond length is 1.89 Å. In the third Pt site, Pt(3) is bonded in a bent 150 degrees geometry to one Ir(2) and one Ir(5) atom.
