Abstract

Pr2Co7 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Pr sites. In the first Pr site, Pr is bonded in a 12-coordinate geometry to twelve Co atoms. There are a spread of Pr–Co bond distances ranging from 2.94–3.20 Å. In the second Pr site, Pr is bonded in a 6-coordinate geometry to eighteen Co atoms. There are a spread of Pr–Co bond distances ranging from 2.93–3.26 Å. There are five inequivalent Co sites. In the first Co site, Co is bonded in a 12-coordinate geometry to three equivalent Pr and six Co atoms. There are three shorter (2.45 Å) and three longer (2.47 Å) Co–Co bond lengths. In the second Co site, Co is bonded to five Pr and seven Co atoms to form a mixture of distorted edge, face, and corner-sharing CoPr5Co7 cuboctahedra. There are a spread of Co–Co bond distances ranging from 2.43–2.61 Å. In the third Co site, Co is bonded to four equivalent Pr and eight Co atoms to form a mixture of edge, face, and corner-sharing CoPr4Co8 cuboctahedra. There are a spread of Co–Co bond distances ranging from 2.48–2.55 Å. In the fourth Co site, Co is bondedmore »« less
