Materials Data on PrZn11 by Materials Project
PrZn11 crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Pr is bonded in a 8-coordinate geometry to eighteen Zn atoms. There are a spread of Pr–Zn bond distances ranging from 3.29–3.43 Å. There are three inequivalent Zn sites. In the first Zn site, Zn is bonded in a 6-coordinate geometry to two equivalent Pr and twelve Zn atoms. There are four shorter (2.80 Å) and eight longer (2.89 Å) Zn–Zn bond lengths. In the second Zn site, Zn is bonded to two equivalent Pr and ten Zn atoms to form a mixture of distorted edge, face, and corner-sharing ZnPr2Zn10 cuboctahedra. There are a spread of Zn–Zn bond distances ranging from 2.60–2.99 Å. In the third Zn site, Zn is bonded in a 12-coordinate geometry to ten Zn atoms.
