Re As Rh Rh
ReRh2As crystallizes in the triclinic P1 space group. Re(1) is bonded in a 2-coordinate geometry to one Rh(1), one Rh(2), and one As(1) atom. The Re(1)-Rh(1) bond length is 1.46 Å. The Re(1)-Rh(2) bond length is 2.32 Å. The Re(1)-As(1) bond length is 1.48 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a single-bond geometry to one Re(1) and two equivalent Rh(2) atoms. There is one shorter (2.24 Å) and one longer (2.28 Å) Rh(1)-Rh(2) bond length. In the second Rh site, Rh(2) is bonded in a 6-coordinate geometry to one Re(1), two equivalent Rh(1), two equivalent Rh(2), and one As(1) atom. Both Rh(2)-Rh(2) bond lengths are 2.91 Å. The Rh(2)-As(1) bond length is 2.27 Å. As(1) is bonded in a 1-coordinate geometry to one Re(1) and one Rh(2) atom.
