Sc Ni Ni Rh
ScRhNi2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ScRhNi2 clusters. Sc(1) is bonded in a 2-coordinate geometry to two equivalent Ni(1) atoms. Both Sc(1)-Ni(1) bond lengths are 0.43 Å. Rh(1) is bonded in a 2-coordinate geometry to two equivalent Ni(1) atoms. Both Rh(1)-Ni(1) bond lengths are 0.89 Å. Ni(1) is bonded in a distorted single-bond geometry to one Sc(1), one Rh(1), and one Ni(1) atom. The Ni(1)-Ni(1) bond length is 0.47 Å.
