Na Zn Zn Co
NaCoZn2 crystallizes in the triclinic P1 space group. Na(1) is bonded in a 2-coordinate geometry to one Co(1), one Zn(1), and two equivalent Zn(2) atoms. The Na(1)-Co(1) bond length is 1.61 Å. The Na(1)-Zn(1) bond length is 1.81 Å. There is one shorter (2.35 Å) and one longer (2.48 Å) Na(1)-Zn(2) bond length. Co(1) is bonded in a distorted single-bond geometry to one Na(1), two equivalent Zn(1), and two equivalent Zn(2) atoms. There is one shorter (2.05 Å) and one longer (2.43 Å) Co(1)-Zn(1) bond length. There is one shorter (2.39 Å) and one longer (2.82 Å) Co(1)-Zn(2) bond length. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 4-coordinate geometry to one Na(1), two equivalent Co(1), and one Zn(2) atom. The Zn(1)-Zn(2) bond length is 1.66 Å. In the second Zn site, Zn(2) is bonded in a 5-coordinate geometry to two equivalent Na(1), two equivalent Co(1), and one Zn(1) atom.
