SmOsAg2 crystallizes in the trigonal R3m space group. Sm(1) is bonded in a single-bond geometry to three equivalent Os(1), one Ag(1), and four equivalent Ag(2) atoms. All Sm(1)-Os(1) bond lengths are 2.77 Å. The Sm(1)-Ag(1) bond length is 0.55 Å. There are three shorter (2.75 Å) and one longer (3.70 Å) Sm(1)-Ag(2) bond length. Os(1) is bonded in a 9-coordinate geometry to three equivalent Sm(1), three equivalent Ag(1), and three equivalent Ag(2) atoms. All Os(1)-Ag(1) bond lengths are 2.75 Å. All Os(1)-Ag(2) bond lengths are 2.75 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a single-bond geometry to one Sm(1) and three equivalent Os(1) atoms. In the second Ag site, Ag(2) is bonded to four equivalent Sm(1) and three equivalent Os(1) atoms to form a mixture of distorted corner and edge-sharing AgSm4Os3 hexagonal pyramids.
