PmRhO3 is Copper structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one PmRhO3 cluster. Pm(1) is bonded in a single-bond geometry to one Rh(1) and one O(1) atom. The Pm(1)-Rh(1) bond length is 0.13 Å. The Pm(1)-O(1) bond length is 1.98 Å. Rh(1) is bonded in a single-bond geometry to one Pm(1) and two equivalent O(1) atoms. There is one shorter (1.58 Å) and one longer (1.90 Å) Rh(1)-O(1) bond length. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to one Pm(1), two equivalent Rh(1), one O(2), and one O(3) atom. The O(1)-O(2) bond length is 0.95 Å. The O(1)-O(3) bond length is 0.94 Å. In the second O site, O(2) is bonded in a distorted single-bond geometry to one O(1) and one O(3) atom. The O(2)-O(3) bond length is 0.21 Å. In the third O site, O(3) is bonded in a 1-coordinate geometry to one O(1) and one O(2) atom.
