K Be Zn Zn
KBeZn2 crystallizes in the triclinic P1 space group. K(1) is bonded in a single-bond geometry to one Be(1), one Zn(2), and three equivalent Zn(1) atoms. The K(1)-Be(1) bond length is 0.85 Å. The K(1)-Zn(2) bond length is 3.11 Å. There are a spread of K(1)-Zn(1) bond distances ranging from 3.11-3.66 Å. Be(1) is bonded in a single-bond geometry to one K(1) and one Zn(2) atom. The Be(1)-Zn(2) bond length is 2.78 Å. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 6-coordinate geometry to three equivalent K(1), one Zn(2), and two equivalent Zn(1) atoms. The Zn(1)-Zn(2) bond length is 2.08 Å. Both Zn(1)-Zn(1) bond lengths are 2.88 Å. In the second Zn site, Zn(2) is bonded in a 5-coordinate geometry to one K(1), one Be(1), one Zn(1), and two equivalent Zn(2) atoms. Both Zn(2)-Zn(2) bond lengths are 2.88 Å.
