Title: Materials Data on Mg149V by Materials Project

Abstract

Mg149V is alpha Samarium-derived structured and crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. there are twenty-seven inequivalent Mg sites. In the first Mg site, Mg is bonded to twelve Mg atoms to form MgMg12 cuboctahedra that share a cornercorner with one VMg12 cuboctahedra, corners with seventeen MgMg12 cuboctahedra, edges with eighteen MgMg11V cuboctahedra, and faces with twenty MgMg12 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.17–3.23 Å. In the second Mg site, Mg is bonded to eleven Mg and one V atom to form distorted MgMg11V cuboctahedra that share corners with eighteen MgMg12 cuboctahedra, edges with eighteen MgMg12 cuboctahedra, a faceface with one VMg12 cuboctahedra, and faces with nineteen MgMg12 cuboctahedra.
