Materials Data on Be3Tc by Materials Project

Abstract

Be3Tc is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Be is bonded to eight equivalent Be and four equivalent Tc atoms to form BeBe8Tc4 cuboctahedra that share corners with twelve equivalent BeBe8Tc4 cuboctahedra, edges with eight equivalent TcBe12 cuboctahedra, edges with sixteen equivalent BeBe8Tc4 cuboctahedra, faces with four equivalent TcBe12 cuboctahedra, and faces with fourteen equivalent BeBe8Tc4 cuboctahedra. All Be–Be bond lengths are 2.39 Å. All Be–Tc bond lengths are 2.39 Å. Tc is bonded to twelve equivalent Be atoms to form TcBe12 cuboctahedra that share corners with twelve equivalent TcBe12 cuboctahedra, edges with twenty-four equivalent BeBe8Tc4 cuboctahedra, faces with six equivalent TcBe12 cuboctahedra, and faces with twelve equivalent BeBe8Tc4 cuboctahedra.
