Ta Ni Ag Ag
TaNiAg2 crystallizes in the triclinic P1 space group. Ta(1) is bonded in a 6-coordinate geometry to four equivalent Ta(1), one Ag(1), and one Ag(2) atom. All Ta(1)-Ta(1) bond lengths are 2.74 Å. The Ta(1)-Ag(1) bond length is 3.50 Å. The Ta(1)-Ag(2) bond length is 3.50 Å. Ni(1) is bonded in a distorted single-bond geometry to one Ag(1) and one Ag(2) atom. The Ni(1)-Ag(1) bond length is 1.92 Å. The Ni(1)-Ag(2) bond length is 0.95 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted single-bond geometry to one Ta(1) and one Ni(1) atom. In the second Ag site, Ag(2) is bonded in a distorted single-bond geometry to one Ta(1) and one Ni(1) atom.
