Materials Data on Zn11Co2 by Materials Project
Co2Zn11 crystallizes in the cubic I-43m space group. The structure is three-dimensional. Co is bonded in a distorted q6 geometry to twelve Zn atoms. There are a spread of Co–Zn bond distances ranging from 2.54–2.73 Å. There are three inequivalent Zn sites. In the first Zn site, Zn is bonded in a 7-coordinate geometry to two equivalent Co and eleven Zn atoms. There are a spread of Zn–Zn bond distances ranging from 2.61–3.01 Å. In the second Zn site, Zn is bonded in a 2-coordinate geometry to two equivalent Co and five Zn atoms. The Zn–Zn bond length is 2.61 Å. In the third Zn site, Zn is bonded in a 12-coordinate geometry to three equivalent Co and nine Zn atoms. All Zn–Zn bond lengths are 2.64 Å.
