Eu Rh
EuRh is alpha carbon monoxide-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two EuRh clusters. Eu(1) is bonded in a single-bond geometry to one Rh(1) atom. The Eu(1)-Rh(1) bond length is 0.63 Å. Rh(1) is bonded in a single-bond geometry to one Eu(1) atom.
