Li Li Pm Rh
Li2PmRh crystallizes in the trigonal R3m space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 10-coordinate geometry to four equivalent Li(2), three equivalent Pm(1), and three equivalent Rh(1) atoms. There is one shorter (2.78 Å) and three longer (2.82 Å) Li(1)-Li(2) bond lengths. All Li(1)-Pm(1) bond lengths are 2.70 Å. All Li(1)-Rh(1) bond lengths are 2.70 Å. In the second Li site, Li(2) is bonded in a single-bond geometry to four equivalent Li(1), three equivalent Pm(1), and one Rh(1) atom. All Li(2)-Pm(1) bond lengths are 2.70 Å. The Li(2)-Rh(1) bond length is 1.46 Å. Pm(1) is bonded in a 10-coordinate geometry to three equivalent Li(1), three equivalent Li(2), and four equivalent Rh(1) atoms. There is one shorter (2.78 Å) and three longer (2.82 Å) Pm(1)-Rh(1) bond lengths. Rh(1) is bonded in a single-bond geometry to one Li(2), three equivalent Li(1), and four equivalent Pm(1) atoms.
