Ag Rh Rh Rh
Rh3Ag crystallizes in the triclinic P1 space group. There are three inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 4-coordinate geometry to one Rh(2), two equivalent Rh(3), and two equivalent Ag(1) atoms. The Rh(1)-Rh(2) bond length is 2.17 Å. There is one shorter (2.37 Å) and one longer (2.54 Å) Rh(1)-Rh(3) bond length. There is one shorter (2.64 Å) and one longer (2.69 Å) Rh(1)-Ag(1) bond length. In the second Rh site, Rh(2) is bonded in a distorted single-bond geometry to one Rh(1), two equivalent Rh(3), and one Ag(1) atom. There is one shorter (2.20 Å) and one longer (2.72 Å) Rh(2)-Rh(3) bond length. The Rh(2)-Ag(1) bond length is 1.80 Å. In the third Rh site, Rh(3) is bonded in a 8-coordinate geometry to two equivalent Rh(1), two equivalent Rh(2), two equivalent Rh(3), and two equivalent Ag(1) atoms. Both Rh(3)-Rh(3) bond lengths are 2.77 Å. There is one shorter (2.64 Å) and one longer (2.69 Å) Rh(3)-Ag(1) bond length. Ag(1) is bonded in a distorted single-bond geometry to one Rh(2), two equivalent Rh(1), and two equivalent Rh(3) atoms.
