SrMoIrNi crystallizes in the trigonal R3m space group. Sr(1) is bonded in a 10-coordinate geometry to three equivalent Mo(1), four equivalent Ir(1), and three equivalent Ni(1) atoms. All Sr(1)-Mo(1) bond lengths are 2.70 Å. There is one shorter (2.64 Å) and three longer (2.86 Å) Sr(1)-Ir(1) bond lengths. All Sr(1)-Ni(1) bond lengths are 2.70 Å. Mo(1) is bonded in a 10-coordinate geometry to three equivalent Sr(1), three equivalent Ir(1), and four equivalent Ni(1) atoms. All Mo(1)-Ir(1) bond lengths are 2.70 Å. There is one shorter (2.64 Å) and three longer (2.86 Å) Mo(1)-Ni(1) bond lengths. Ir(1) is bonded in a 2-coordinate geometry to four equivalent Sr(1), three equivalent Mo(1), and one Ni(1) atom. The Ir(1)-Ni(1) bond length is 1.64 Å. Ni(1) is bonded in a distorted single-bond geometry to three equivalent Sr(1), four equivalent Mo(1), and one Ir(1) atom.
