RhB4O2(BO2)2 crystallizes in the monoclinic C2/m space group. The structure is zero-dimensional and consists of four dihydroxyboranyl molecules and two RhB4O2 clusters. In each RhB4O2 cluster, Rh(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent B(2) atoms. B(2) is bonded in a single-bond geometry to one Rh(1) and one O(2) atom. O(2) is bonded in an L-shaped geometry to two equivalent B(2) atoms.

In each RhB4O2 cluster, Rh(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent B(2) atoms. All Rh(1)-B(2) bond lengths are 2.25 Å. B(2) is bonded in a single-bond geometry to one Rh(1) and one O(2) atom. The B(2)-O(2) bond length is 1.37 Å. O(2) is bonded in an L-shaped geometry to two equivalent B(2) atoms.
