Materials Data on Pr7CoI12 by Materials Project
Pr7CoI12 is trigonal omega-derived structured and crystallizes in the trigonal R-3 space group. The structure is three-dimensional. there are two inequivalent Pr sites. In the first Pr site, Pr is bonded to one Co and five I atoms to form a mixture of distorted edge and corner-sharing PrCoI5 octahedra. The corner-sharing octahedra tilt angles range from 0–8°. The Pr–Co bond length is 2.78 Å. There are a spread of Pr–I bond distances ranging from 3.21–3.52 Å. In the second Pr site, Pr is bonded to six equivalent I atoms to form edge-sharing PrI6 octahedra. All Pr–I bond lengths are 3.17 Å. Co is bonded in an octahedral geometry to six equivalent Pr atoms. There are two inequivalent I sites. In the first I site, I is bonded in a distorted T-shaped geometry to three Pr atoms. In the second I site, I is bonded in a distorted T-shaped geometry to three equivalent Pr atoms.
