Ag Ag Ag Ag Os W
WOsAg4 crystallizes in the trigonal R3m space group. W(1) is bonded in a 7-coordinate geometry to one Ag(2) and six equivalent Ag(1) atoms. The W(1)-Ag(2) bond length is 2.91 Å. All W(1)-Ag(1) bond lengths are 2.81 Å. Os(1) is bonded in a 6-coordinate geometry to three equivalent Ag(1) and three equivalent Ag(2) atoms. All Os(1)-Ag(1) bond lengths are 1.68 Å. All Os(1)-Ag(2) bond lengths are 3.30 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 2-coordinate geometry to two equivalent W(1), one Os(1), one Ag(2), and two equivalent Ag(1) atoms. The Ag(1)-Ag(2) bond length is 1.39 Å. Both Ag(1)-Ag(1) bond lengths are 0.80 Å. In the second Ag site, Ag(2) is bonded in a 7-coordinate geometry to one W(1), three equivalent Os(1), and three equivalent Ag(1) atoms.
