Materials Data on Mg14FeC by Materials Project
Abstract
Mg14FeC crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional and consists of one methane molecule and one Mg14Fe framework. In the Mg14Fe framework, there are four inequivalent Mg sites. In the first Mg site, Mg is bonded to ten Mg and two equivalent Fe atoms to form distorted MgMg10Fe2 cuboctahedra that share corners with six equivalent MgMg10Fe2 cuboctahedra, edges with two equivalent FeMg12 cuboctahedra, edges with eight MgMg10Fe2 cuboctahedra, faces with two equivalent FeMg12 cuboctahedra, and faces with six MgMg10Fe2 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.04–3.09 Å. Both Mg–Fe bond lengths are 3.09 Å. In the second Mg site, Mg is bonded in a 10-coordinate geometry to two equivalent Mg atoms. Both Mg–Mg bond lengths are 3.05 Å. In the third Mg site, Mg is bonded in a 1-coordinate geometry to four Mg and one Fe atom. Both Mg–Mg bond lengths are 3.09 Å. The Mg–Fe bond length is 3.01 Å. In the fourth Mg site, Mg is bonded to twelve Mg atoms to form MgMg12 cuboctahedra that share corners with six equivalent MgMg12 cuboctahedra, edges with six equivalent MgMg10Fe2 cuboctahedra, faces with three equivalent FeMg12 cuboctahedra, and faces with fivemore »
