As As Rh Br
RhAs2Br crystallizes in the triclinic P1 space group. Rh(1) is bonded in a 4-coordinate geometry to one As(2), two equivalent As(1), and one Br(1) atom. The Rh(1)-As(2) bond length is 2.37 Å. There is one shorter (2.59 Å) and one longer (2.60 Å) Rh(1)-As(1) bond length. The Rh(1)-Br(1) bond length is 2.69 Å. There are two inequivalent As sites. In the first As site, As(1) is bonded in a single-bond geometry to two equivalent Rh(1) and one Br(1) atom. The As(1)-Br(1) bond length is 1.40 Å. In the second As site, As(2) is bonded in a 1-coordinate geometry to one Rh(1) and one Br(1) atom. The As(2)-Br(1) bond length is 2.33 Å. Br(1) is bonded in a distorted single-bond geometry to one Rh(1), one As(1), and one As(2) atom.
