SrOsZnBi crystallizes in the trigonal R3m space group. Sr(1) is bonded in a distorted linear geometry to four equivalent Os(1), three equivalent Zn(1), and one Bi(1) atom. There is one shorter (2.61 Å) and three longer (3.29 Å) Sr(1)-Os(1) bond lengths. All Sr(1)-Zn(1) bond lengths are 3.12 Å. The Sr(1)-Bi(1) bond length is 2.61 Å. Os(1) is bonded in a 10-coordinate geometry to four equivalent Sr(1), three equivalent Zn(1), and three equivalent Bi(1) atoms. All Os(1)-Zn(1) bond lengths are 2.95 Å. All Os(1)-Bi(1) bond lengths are 3.12 Å. Zn(1) is bonded in a 10-coordinate geometry to three equivalent Sr(1), three equivalent Os(1), and four equivalent Bi(1) atoms.
