Ba Ba Ni Rh
Ba2RhNi crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ba2RhNi clusters. Ba(1) is bonded in a 2-coordinate geometry to one Rh(1) and one Ni(1) atom. The Ba(1)-Rh(1) bond length is 1.56 Å. The Ba(1)-Ni(1) bond length is 1.56 Å. Rh(1) is bonded in a 2-coordinate geometry to two equivalent Ba(1) atoms. Ni(1) is bonded in a 2-coordinate geometry to two equivalent Ba(1) atoms.
