Title: Materials Data on Ac3Np by Materials Project

Abstract

NpAc3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Np is bonded to twelve equivalent Ac atoms to form NpAc12 cuboctahedra that share corners with six equivalent NpAc12 cuboctahedra, corners with twelve equivalent AcAc8Np4 cuboctahedra, edges with eighteen equivalent AcAc8Np4 cuboctahedra, faces with eight equivalent NpAc12 cuboctahedra, and faces with twelve equivalent AcAc8Np4 cuboctahedra. There are six shorter (3.79 Å) and six longer (3.89 Å) Np–Ac bond lengths. Ac is bonded to four equivalent Np and eight equivalent Ac atoms to form distorted AcAc8Np4 cuboctahedra that share corners with four equivalent NpAc12 cuboctahedra, corners with fourteen equivalent AcAc8Np4 cuboctahedra, edges with six equivalent NpAc12 cuboctahedra, edges with twelve equivalent AcAc8Np4 cuboctahedra, faces with four equivalent NpAc12 cuboctahedra, and faces with sixteen equivalent AcAc8Np4 cuboctahedra. There are a spread of Ac–Ac bond distances ranging from 3.79–3.99 Å.
