Materials Data on Ce2MgCo9 by Materials Project
Abstract
Ce2MgCo9 is Frank-Kasper $$\mu$$ Phase-derived structured and crystallizes in the trigonal R3m space group. The structure is three-dimensional. Mg is bonded in a 12-coordinate geometry to four Ce and twelve Co atoms. There are three shorter (3.12 Å) and one longer (3.33 Å) Mg–Ce bond lengths. There are a spread of Mg–Co bond distances ranging from 2.82–3.01 Å. There are two inequivalent Ce sites. In the first Ce site, Ce is bonded in a 6-coordinate geometry to one Mg and eighteen Co atoms. There are a spread of Ce–Co bond distances ranging from 2.85–3.22 Å. In the second Ce site, Ce is bonded in a 12-coordinate geometry to three equivalent Mg and twelve Co atoms. There are a spread of Ce–Co bond distances ranging from 2.83–2.99 Å. There are five inequivalent Co sites. In the first Co site, Co is bonded in a 12-coordinate geometry to three equivalent Ce and nine Co atoms. There are a spread of Co–Co bond distances ranging from 2.45–2.85 Å. In the second Co site, Co is bonded in a 12-coordinate geometry to three equivalent Ce and nine Co atoms. There are three shorter (2.46 Å) and three longer (2.47 Å) Co–Co bond lengths. In the third Co site, Co is bonded to one Mg, four Ce, and seven Co atoms to form a mixture of distorted face, edge, and corner-sharing CoCe4MgCo7 cuboctahedra. There are a spread of Co–Co bond distances ranging from 2.44–2.51 Å. In the fourth Co site, Co is bonded to two equivalent Mg, three Ce, and seven Co atoms to form a mixture of face, edge, and corner-sharing CoCe3Mg2Co7 cuboctahedra. There are a spread of Co–Co bond distances ranging from 2.44–2.48 Å. In the fifth Co site, Co is bonded to three equivalent Mg, three equivalent Ce, and six Co atoms to form CoCe3Mg3Co6 cuboctahedra that share corners with twelve CoCe4MgCo7 cuboctahedra, edges with six equivalent CoCe3Mg3Co6 cuboctahedra, and faces with eighteen CoCe4MgCo7 cuboctahedra.
