The material structure described by Be3Ni is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Be(1) is bonded to eight equivalent Be(1) and four equivalent Ni(1) atoms to form distorted BeBe8Ni4 cuboctahedra that share corners with four equivalent Ni(1)Be12 cuboctahedra, corners with fourteen equivalent Be(1)Be8Ni4 cuboctahedra, edges with six equivalent Ni(1)Be12 cuboctahedra, edges with twelve equivalent Be(1)Be8Ni4 cuboctahedra, faces with four equivalent Ni(1)Be12 cuboctahedra, and faces with sixteen equivalent Be(1)Be8Ni4 cuboctahedra. Ni(1) is bonded to twelve equivalent Be(1) atoms to form NiBe12 cuboctahedra that share corners with six equivalent Ni(1)Be12 cuboctahedra, corners with twelve equivalent Be(1)Be8Ni4 cuboctahedra, edges with eighteen equivalent Be(1)Be8Ni4 cuboctahedra, faces with eight equivalent Ni(1)Be12 cuboctahedra, and faces with twelve equivalent Be(1)Be8Ni4 cuboctahedra. is represented by the CIF file [CIF]
