Os2AgBr crystallizes in the trigonal R3m space group. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 7-coordinate geometry to one Os(2), three equivalent Ag(1), and three equivalent Br(1) atoms. The Os(1)-Os(2) bond length is 2.04 Å. All Os(1)-Ag(1) bond lengths are 2.73 Å. All Os(1)-Br(1) bond lengths are 2.73 Å. In the second Os site, Os(2) is bonded in a 8-coordinate geometry to one Os(1), three equivalent Ag(1), and four equivalent Br(1) atoms. All Os(2)-Ag(1) bond lengths are 2.73 Å. There is one shorter (2.45 Å) and three longer (2.87 Å) Os(2)-Br(1) bond lengths. Ag(1) is bonded in a distorted single-bond geometry to three equivalent Os(1), three equivalent Os(2), and one Br(1) atom. The Ag(1)-Br(1) bond length is 2.04 Å. Br(1) is bonded in a 1-coordinate geometry to three equivalent Os(1), four equivalent Os(2), and one Ag(1) atom.
