Materials Data on Pr5Co2 by Materials Project
Pr5Co2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are three inequivalent Pr sites. In the first Pr site, Pr is bonded in a distorted bent 150 degrees geometry to three equivalent Co atoms. There are a spread of Pr–Co bond distances ranging from 2.75–3.66 Å. In the second Pr site, Pr is bonded to four equivalent Co atoms to form distorted edge-sharing PrCo4 tetrahedra. There are two shorter (2.93 Å) and two longer (2.99 Å) Pr–Co bond lengths. In the third Pr site, Pr is bonded in a 2-coordinate geometry to three equivalent Co atoms. There are a spread of Pr–Co bond distances ranging from 2.81–3.30 Å. Co is bonded in a 7-coordinate geometry to eight Pr atoms.
