HfNiAg2 crystallizes in the triclinic P1 space group. Hf(1) is bonded in a 3-coordinate geometry to one Ni(1), one Ag(2), and two equivalent Ag(1) atoms. The Hf(1)-Ni(1) bond length is 2.20 Å. The Hf(1)-Ag(2) bond length is 2.41 Å. There is one shorter (2.41 Å) and one longer (3.17 Å) Hf(1)-Ag(1) bond length. Ni(1) is bonded in a 1-coordinate geometry to one Hf(1) and two equivalent Ag(1) atoms. There is one shorter (2.17 Å) and one longer (3.00 Å) Ni(1)-Ag(1) bond length. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 8-coordinate geometry to two equivalent Hf(1), two equivalent Ni(1), two equivalent Ag(1), and two equivalent Ag(2) atoms. Both Ag(1)-Ag(1) bond lengths are 2.88 Å. There is one shorter (2.16 Å) and one longer (2.77 Å) Ag(1)-Ag(2) bond length. In the second Ag site, Ag(2) is bonded in a 1-coordinate geometry to one Hf(1) and two equivalent Ag(1) atoms.
