MnRh2O4 crystallizes in the trigonal R3m space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a distorted trigonal planar geometry to one Mn(2) and three equivalent Rh(1) atoms. The Mn(1)-Mn(2) bond length is 2.90 Å. All Mn(1)-Rh(1) bond lengths are 2.91 Å. In the second Mn site, Mn(2) is bonded in a 4-coordinate geometry to one Mn(1) and three equivalent Rh(1) atoms. All Mn(2)-Rh(1) bond lengths are 2.51 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a single-bond geometry to one Mn(1), one Mn(2), and one O(3) atom. The Rh(1)-O(3) bond length is 0.66 Å. In the second Rh site, Rh(2) is bonded in a linear geometry to one O(1) and one O(4) atom. The Rh(2)-O(1) bond length is 1.15 Å. The Rh(2)-O(4) bond length is 1.15 Å. There are four inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one Rh(2) and three equivalent O(2) atoms. All O(1)-O(2) bond lengths are 0.43 Å. In the second O site, O(2) is bonded in a 3-coordinate geometry to one O(1) and two equivalent O(2) atoms. Both O(2)-O(2) bond lengths are 0.25 Å. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Rh(1), one O(4), and two equivalent O(3) atoms. The O(3)-O(4) bond length is 0.43 Å. Both O(3)-O(3) bond lengths are 0.25 Å. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one Rh(2) and three equivalent O(3) atoms.
