Title: Materials Data on Mg2PbW by Materials Project

Abstract

Mg2WPb is Zintl Phase-derived structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. there are two inequivalent Mg sites. In the first Mg site, Mg is bonded to four equivalent W atoms to form distorted MgW4 tetrahedra that share corners with four equivalent PbMg4W4 tetrahedra, corners with twenty-four MgW4 tetrahedra, edges with six equivalent PbMg4W4 tetrahedra, and faces with four equivalent MgPb4W6 tetrahedra. All Mg–W bond lengths are 2.98 Å. In the second Mg site, Mg is bonded to six equivalent W and four equivalent Pb atoms to form distorted MgPb4W6 tetrahedra that share corners with four equivalent WMg10Pb4 tetrahedra, corners with twelve equivalent PbMg4W4 tetrahedra, corners with eighteen MgW4 tetrahedra, edges with six equivalent WMg10Pb4 tetrahedra, faces with four equivalent PbMg4W4 tetrahedra, and faces with sixteen MgPb4W6 tetrahedra. All Mg–W bond lengths are 3.45 Å. All Mg–Pb bond lengths are 2.98 Å. W is bonded to ten Mg and four equivalent Pb atoms to form distorted WMg10Pb4 tetrahedra that share corners with four equivalent MgPb4W6 tetrahedra, corners with six equivalent WMg10Pb4 tetrahedra, corners with twelve equivalent PbMg4W4 tetrahedra, edges with six equivalent MgPb4W6 tetrahedra, faces with four equivalent PbMg4W4 tetrahedra, and faces with twelve equivalentmore » WMg10Pb4 tetrahedra.
