Cr2RhAs crystallizes in the triclinic P1 space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a 3-coordinate geometry to two equivalent Cr(2), two equivalent Rh(1), and two equivalent As(1) atoms. There is one shorter (1.68 Å) and one longer (2.82 Å) Cr(1)-Cr(2) bond length. There is one shorter (1.92 Å) and one longer (2.22 Å) Cr(1)-Rh(1) bond length. There is one shorter (2.28 Å) and one longer (2.54 Å) Cr(1)-As(1) bond length. In the second Cr site, Cr(2) is bonded in a 6-coordinate geometry to two equivalent Cr(1), two equivalent Rh(1), and two equivalent As(1) atoms. There is one shorter (2.28 Å) and one longer (2.54 Å) Cr(2)-Rh(1) bond length. There is one shorter (1.92 Å) and one longer (2.22 Å) Cr(2)-As(1) bond length. Rh(1) is bonded in a 5-coordinate geometry to two equivalent Cr(1), two equivalent Cr(2), and one As(1) atom. The Rh(1)-As(1) bond length is 1.48 Å. As(1) is bonded in a 5-coordinate geometry to two equivalent Cr(1), two equivalent Cr(2), and one Rh(1) atom.
