Os4CoAg crystallizes in the trigonal R3m space group. There are two inequivalent Os sites. In the first Os site, Os(2) is bonded in a 10-coordinate geometry to three equivalent Os(1), four equivalent Co(1), and three equivalent Ag(1) atoms. All Os(2)-Os(1) bond lengths are 1.57 Å. There are three shorter (3.03 Å) and one longer (3.55 Å) Os(2)-Co(1) bond length. All Os(2)-Ag(1) bond lengths are 3.06 Å. In the second Os site, Os(1) is bonded in a 2-coordinate geometry to one Os(2), two equivalent Os(1), two equivalent Co(1), and two equivalent Ag(1) atoms. Both Os(1)-Os(1) bond lengths are 0.90 Å. Both Os(1)-Co(1) bond lengths are 2.87 Å. There is one shorter (2.03 Å) and one longer (3.31 Å) Os(1)-Ag(1) bond length. Co(1) is bonded in a 13-coordinate geometry to four equivalent Os(2), six equivalent Os(1), and three equivalent Ag(1) atoms. All Co(1)-Ag(1) bond lengths are 3.27 Å. Ag(1) is bonded in a 12-coordinate geometry to three equivalent Os(2), six equivalent Os(1), and three equivalent Co(1) atoms.
