Zr Ni Ag Ag
ZrNiAg2 crystallizes in the monoclinic Cm space group. Zr(1) is bonded in a single-bond geometry to three equivalent Ni(1) and one Ag(2) atom. There is one shorter (3.23 Å) and two longer (3.51 Å) Zr(1)-Ni(1) bond lengths. The Zr(1)-Ag(2) bond length is 0.04 Å. Ni(1) is bonded in a 4-coordinate geometry to three equivalent Zr(1) and one Ag(1) atom. The Ni(1)-Ag(1) bond length is 2.66 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 9-coordinate geometry to one Ni(1), four equivalent Ag(1), and four equivalent Ag(2) atoms. All Ag(1)-Ag(1) bond lengths are 3.19 Å. There are a spread of Ag(1)-Ag(2) bond distances ranging from 2.36-3.07 Å. In the second Ag site, Ag(2) is bonded in a single-bond geometry to one Zr(1) and four equivalent Ag(1) atoms.
