Ni Ni Ag Ir
IrNi2Ag crystallizes in the triclinic P1 space group. Ir(1) is bonded in a 1-coordinate geometry to one Ni(2), two equivalent Ni(1), and one Ag(1) atom. The Ir(1)-Ni(2) bond length is 1.95 Å. There is one shorter (2.32 Å) and one longer (2.77 Å) Ir(1)-Ni(1) bond length. The Ir(1)-Ag(1) bond length is 1.07 Å. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 8-coordinate geometry to two equivalent Ir(1), two equivalent Ni(1), two equivalent Ni(2), and two equivalent Ag(1) atoms. Both Ni(1)-Ni(1) bond lengths are 2.68 Å. There is one shorter (1.69 Å) and one longer (2.87 Å) Ni(1)-Ni(2) bond length. There is one shorter (1.95 Å) and one longer (2.47 Å) Ni(1)-Ag(1) bond length. In the second Ni site, Ni(2) is bonded in a 2-coordinate geometry to one Ir(1) and two equivalent Ni(1) atoms. Ag(1) is bonded in a distorted single-bond geometry to one Ir(1) and two equivalent Ni(1) atoms.
