Ag Rh Rh Br
Rh2AgBr crystallizes in the monoclinic Pm space group. Rh(1) is bonded in a 8-coordinate geometry to four equivalent Rh(1), two equivalent Ag(1), and two equivalent Br(1) atoms. There are a spread of Rh(1)-Rh(1) bond distances ranging from 1.77-3.00 Å. Both Rh(1)-Ag(1) bond lengths are 2.81 Å. Both Rh(1)-Br(1) bond lengths are 2.81 Å. Ag(1) is bonded in a single-bond geometry to four equivalent Rh(1) and one Br(1) atom. The Ag(1)-Br(1) bond length is 0.33 Å. Br(1) is bonded in a single-bond geometry to four equivalent Rh(1) and one Ag(1) atom.
