Cr2Rh3 crystallizes in the triclinic P1 space group. There are four inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a single-bond geometry to one Rh(3) and one Rh(4) atom. The Cr(1)-Rh(3) bond length is 2.15 Å. The Cr(1)-Rh(4) bond length is 0.65 Å. In the second Cr site, Cr(2) is bonded in a distorted single-bond geometry to one Cr(3), one Rh(3), one Rh(4), and one Rh(5) atom. The Cr(2)-Cr(3) bond length is 1.73 Å. The Cr(2)-Rh(3) bond length is 2.96 Å. The Cr(2)-Rh(4) bond length is 0.99 Å. The Cr(2)-Rh(5) bond length is 2.28 Å. In the third Cr site, Cr(3) is bonded in a 3-coordinate geometry to one Cr(2), one Rh(1), one Rh(5), and two equivalent Rh(3) atoms. The Cr(3)-Rh(1) bond length is 2.01 Å. The Cr(3)-Rh(5) bond length is 2.10 Å. There is one shorter (2.96 Å) and one longer (3.16 Å) Cr(3)-Rh(3) bond length. In the fourth Cr site, Cr(4) is bonded in a distorted water-like geometry to one Rh(2), one Rh(5), and one Rh(6) atom. The Cr(4)-Rh(2) bond length is 0.58 Å. The Cr(4)-Rh(5) bond length is 2.38 Å. The Cr(4)-Rh(6) bond length is 0.21 Å. There are six inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 2-coordinate geometry to one Cr(3) and one Rh(5) atom. The Rh(1)-Rh(5) bond length is 1.75 Å. In the second Rh site, Rh(2) is bonded in a single-bond geometry to one Cr(4) atom. In the third Rh site, Rh(3) is bonded in a 6-coordinate geometry to one Cr(1), one Cr(2), two equivalent Cr(3), one Rh(4), and one Rh(6) atom. The Rh(3)-Rh(4) bond length is 2.05 Å. The Rh(3)-Rh(6) bond length is 2.10 Å. In the fourth Rh site, Rh(4) is bonded in a 2-coordinate geometry to one Cr(1), one Cr(2), and one Rh(3) atom. In the fifth Rh site, Rh(5) is bonded in a 4-coordinate geometry to one Cr(2), one Cr(3), one Cr(4), and one Rh(1) atom. In the sixth Rh site, Rh(6) is bonded in a single-bond geometry to one Cr(4) and one Rh(3) atom.
