K Y Y Zn
KY2Zn crystallizes in the monoclinic Cm space group. K(1) is bonded to eight equivalent Y(1) and four equivalent Zn(1) atoms to form a mixture of distorted face and corner-sharing KY8Zn4 cuboctahedra. There are a spread of K(1)-Y(1) bond distances ranging from 3.11-3.99 Å. There are a spread of K(1)-Zn(1) bond distances ranging from 3.10-3.82 Å. Y(1) is bonded in a 11-coordinate geometry to four equivalent K(1), four equivalent Y(1), and three equivalent Zn(1) atoms. There are a spread of Y(1)-Y(1) bond distances ranging from 3.10-3.82 Å. There are a spread of Y(1)-Zn(1) bond distances ranging from 3.11-3.66 Å. Zn(1) is bonded in a 10-coordinate geometry to four equivalent K(1) and six equivalent Y(1) atoms.
