Th Th Th Th Ag Ag
Th2Ag crystallizes in the triclinic P1 space group. There are four inequivalent Th sites. In the first Th site, Th(1) is bonded in a 4-coordinate geometry to one Th(3), one Th(4), one Ag(1), and one Ag(2) atom. The Th(1)-Th(3) bond length is 2.19 Å. The Th(1)-Th(4) bond length is 2.22 Å. The Th(1)-Ag(1) bond length is 3.23 Å. The Th(1)-Ag(2) bond length is 3.00 Å. In the second Th site, Th(2) is bonded in a 3-coordinate geometry to one Th(3), one Th(4), and one Ag(2) atom. The Th(2)-Th(3) bond length is 2.22 Å. The Th(2)-Th(4) bond length is 2.19 Å. The Th(2)-Ag(2) bond length is 2.77 Å. In the third Th site, Th(3) is bonded in a 2-coordinate geometry to one Th(1), one Th(2), and one Th(4) atom. The Th(3)-Th(4) bond length is 3.23 Å. In the fourth Th site, Th(4) is bonded in a 4-coordinate geometry to one Th(1), one Th(2), one Th(3), and one Ag(1) atom. The Th(4)-Ag(1) bond length is 3.53 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted single-bond geometry to one Th(1), one Th(4), and one Ag(2) atom. The Ag(1)-Ag(2) bond length is 0.36 Å. In the second Ag site, Ag(2) is bonded in a 3-coordinate geometry to one Th(1), one Th(2), and one Ag(1) atom.
