Mo Mo Rh Rh
MoRh crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two MoRh clusters. Mo(1) is bonded in a single-bond geometry to one Rh(1) atom. The Mo(1)-Rh(1) bond length is 0.64 Å. Rh(1) is bonded in a distorted single-bond geometry to one Mo(1) atom.
