NbMoMoRh is alpha oxygen-derived structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one molybdenum--rhodium (1/1) molecule and one NbMo cluster. In the NbMo cluster, Nb(1) is bonded in a single-bond geometry to one Mo(1) atom. The Nb(1)-Mo(1) bond length is 0.81 Å. Mo(1) is bonded in a single-bond geometry to one Nb(1) atom.
