The material structure described by MgTa is beta-prime cadmium gold structured and crystallizes in the orthorhombic Pmma space group. Mg(1) is bonded to four equivalent Mg(1) and eight equivalent Ta(1) atoms to form MgMg4Ta8 cuboctahedra that share corners with eight equivalent Ta(1)Mg8Ta4 cuboctahedra, corners with ten equivalent Mg(1)Mg4Ta8 cuboctahedra, edges with six equivalent Mg(1)Mg4Ta8 cuboctahedra, edges with twelve equivalent Ta(1)Mg8Ta4 cuboctahedra, faces with eight equivalent Ta(1)Mg8Ta4 cuboctahedra, and faces with twelve equivalent Mg(1)Mg4Ta8 cuboctahedra.
