LaTi2Ir crystallizes in the trigonal R3m space group. La(1) is bonded in a 11-coordinate geometry to three equivalent Ti(2), four equivalent Ti(1), and four equivalent Ir(1) atoms. All La(1)-Ti(2) bond lengths are 2.80 Å. There are three shorter (2.77 Å) and one longer (3.65 Å) La(1)-Ti(1) bond length. There are three shorter (2.77 Å) and one longer (3.65 Å) La(1)-Ir(1) bond length. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded in a single-bond geometry to four equivalent La(1), one Ti(2), and three equivalent Ir(1) atoms. The Ti(1)-Ti(2) bond length is 0.73 Å. All Ti(1)-Ir(1) bond lengths are 2.80 Å. In the second Ti site, Ti(2) is bonded in a single-bond geometry to three equivalent La(1), one Ti(1), and four equivalent Ir(1) atoms. There are three shorter (2.77 Å) and one longer (3.65 Å) Ti(2)-Ir(1) bond length. Ir(1) is bonded in a 11-coordinate geometry to four equivalent La(1), three equivalent Ti(1), and four equivalent Ti(2) atoms.
