Os4Rh3 crystallizes in the triclinic P1 space group. There are four inequivalent Os sites. In the first Os site, Os(1) is bonded in a 3-coordinate geometry to one Os(3), one Rh(2), and one Rh(3) atom. The Os(1)-Os(3) bond length is 1.68 Å. The Os(1)-Rh(2) bond length is 2.07 Å. The Os(1)-Rh(3) bond length is 1.61 Å. In the second Os site, Os(2) is bonded in a 3-coordinate geometry to one Os(3), one Rh(2), and one Rh(3) atom. The Os(2)-Os(3) bond length is 1.10 Å. The Os(2)-Rh(2) bond length is 2.07 Å. The Os(2)-Rh(3) bond length is 1.61 Å. In the third Os site, Os(3) is bonded in a 2-coordinate geometry to one Os(1), one Os(2), and one Os(4) atom. The Os(3)-Os(4) bond length is 2.40 Å. In the fourth Os site, Os(4) is bonded in a 2-coordinate geometry to one Os(3) and one Rh(3) atom. The Os(4)-Rh(3) bond length is 2.47 Å. There are three inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a distorted bent 120 degrees geometry to one Rh(2) and one Rh(3) atom. The Rh(1)-Rh(2) bond length is 1.23 Å. The Rh(1)-Rh(3) bond length is 1.65 Å. In the second Rh site, Rh(2) is bonded in a 3-coordinate geometry to one Os(1), one Os(2), and one Rh(1) atom. In the third Rh site, Rh(3) is bonded in a 3-coordinate geometry to one Os(1), one Os(2), one Os(4), and one Rh(1) atom.
