Na Zn Zn Rh
NaRhZn2 crystallizes in the monoclinic Pm space group. Na(1) is bonded in a single-bond geometry to one Rh(1) and four equivalent Zn(1) atoms. The Na(1)-Rh(1) bond length is 0.65 Å. There are two shorter (2.97 Å) and two longer (3.08 Å) Na(1)-Zn(1) bond lengths. Rh(1) is bonded in a single-bond geometry to one Na(1) and four equivalent Zn(1) atoms. There are two shorter (2.97 Å) and two longer (3.08 Å) Rh(1)-Zn(1) bond lengths. Zn(1) is bonded in a 5-coordinate geometry to two equivalent Na(1), two equivalent Rh(1), and one Zn(1) atom. The Zn(1)-Zn(1) bond length is 0.98 Å.
