TiMoIrAu crystallizes in the trigonal R3m space group. Ti(1) is bonded in a distorted single-bond geometry to four equivalent Mo(1), three equivalent Ir(1), and one Au(1) atom. There is one shorter (2.64 Å) and three longer (2.79 Å) Ti(1)-Mo(1) bond lengths. All Ti(1)-Ir(1) bond lengths are 2.74 Å. The Ti(1)-Au(1) bond length is 1.90 Å. Mo(1) is bonded in a 8-coordinate geometry to four equivalent Ti(1), one Ir(1), and three equivalent Au(1) atoms. The Mo(1)-Ir(1) bond length is 1.90 Å. All Mo(1)-Au(1) bond lengths are 2.74 Å. Ir(1) is bonded in a 7-coordinate geometry to three equivalent Ti(1), one Mo(1), and three equivalent Au(1) atoms. All Ir(1)-Au(1) bond lengths are 2.74 Å. Au(1) is bonded in a single-bond geometry to one Ti(1), three equivalent Mo(1), and three equivalent Ir(1) atoms.
