Materials Data on YNp3 by Materials Project

Abstract

Np3Y is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Np is bonded to eight equivalent Np and four equivalent Y atoms to form NpY4Np8 cuboctahedra that share corners with twelve equivalent NpY4Np8 cuboctahedra, edges with eight equivalent YNp12 cuboctahedra, edges with sixteen equivalent NpY4Np8 cuboctahedra, faces with four equivalent YNp12 cuboctahedra, and faces with fourteen equivalent NpY4Np8 cuboctahedra. All Np–Np bond lengths are 3.30 Å. All Np–Y bond lengths are 3.30 Å. Y is bonded to twelve equivalent Np atoms to form YNp12 cuboctahedra that share corners with twelve equivalent YNp12 cuboctahedra, edges with twenty-four equivalent NpY4Np8 cuboctahedra, faces with six equivalent YNp12 cuboctahedra, and faces with twelve equivalent NpY4Np8 cuboctahedra.
