Li Nb Rh Rh
LiNbRh2 crystallizes in the monoclinic Cm space group. Li(1) is bonded in a distorted bent 120 degrees geometry to one Rh(1) and three equivalent Rh(2) atoms. The Li(1)-Rh(1) bond length is 1.36 Å. There is one shorter (1.86 Å) and two longer (2.64 Å) Li(1)-Rh(2) bond lengths. Nb(1) is bonded in a 2-coordinate geometry to one Rh(1) and one Rh(2) atom. The Nb(1)-Rh(1) bond length is 1.90 Å. The Nb(1)-Rh(2) bond length is 2.06 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 2-coordinate geometry to one Li(1) and one Nb(1) atom. In the second Rh site, Rh(2) is bonded in a 4-coordinate geometry to three equivalent Li(1) and one Nb(1) atom.
