LaIrPt crystallizes in the trigonal R3m space group. La(1) is bonded in a 7-coordinate geometry to four equivalent Ir(1) and four equivalent Pt(1) atoms. There are three shorter (2.72 Å) and one longer (3.38 Å) La(1)-Ir(1) bond length. There are three shorter (2.70 Å) and one longer (4.02 Å) La(1)-Pt(1) bond length. Ir(1) is bonded to four equivalent La(1) and three equivalent Pt(1) atoms to form a mixture of distorted corner and edge-sharing IrLa4Pt3 hexagonal pyramids. All Ir(1)-Pt(1) bond lengths are 2.70 Å. Pt(1) is bonded in a 7-coordinate geometry to four equivalent La(1) and three equivalent Ir(1) atoms.
