Materials Data on HfMg3 by Materials Project

Abstract

Mg3Hf is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Mg is bonded to eight equivalent Mg and four equivalent Hf atoms to form MgHf4Mg8 cuboctahedra that share corners with twelve equivalent MgHf4Mg8 cuboctahedra, edges with eight equivalent HfMg12 cuboctahedra, edges with sixteen equivalent MgHf4Mg8 cuboctahedra, faces with four equivalent HfMg12 cuboctahedra, and faces with fourteen equivalent MgHf4Mg8 cuboctahedra. All Mg–Mg bond lengths are 3.13 Å. All Mg–Hf bond lengths are 3.13 Å. Hf is bonded to twelve equivalent Mg atoms to form HfMg12 cuboctahedra that share corners with twelve equivalent HfMg12 cuboctahedra, edges with twenty-four equivalent MgHf4Mg8 cuboctahedra, faces with six equivalent HfMg12 cuboctahedra, and faces with twelve equivalent MgHf4Mg8 cuboctahedra.
