The material structure described by TcGa3 is beta Cu3Ti-like structured and crystallizes in the tetragonal I4/mmm space group. Tc(1) is bonded to four equivalent Ga(2) and eight equivalent Ga(1) atoms to form TcGa12 cuboctahedra that share corners with four equivalent Tc(1)Ga12 cuboctahedra, corners with eight equivalent Ga(2)Ga8Tc4 cuboctahedra, edges with eight equivalent Tc(1)Ga12 cuboctahedra, edges with sixteen equivalent Ga(1)Ga8Tc4 cuboctahedra, faces with four equivalent Tc(1)Ga12 cuboctahedra, faces with six equivalent Ga(2)Ga8Tc4 cuboctahedra, and faces with eight equivalent Ga(1)Ga8Tc4 cuboctahedra. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to four equivalent Tc(1), four equivalent Ga(1), and four equivalent Ga(2) atoms to form GaGa8Tc4 cuboctahedra that share corners with twelve equivalent Ga(1)Ga8Tc4 cuboctahedra, edges with eight equivalent Tc(1)Ga12 cuboctahedra, edges with eight equivalent Ga(1)Ga8Tc4 cuboctahedra, edges with eight equivalent Ga(2)Ga8Tc4 cuboctahedra, faces with four equivalent Tc(1)Ga12 cuboctahedra, faces with four equivalent Ga(2)Ga8Tc4 cuboctahedra, and faces with ten equivalent Ga(1)Ga8Tc4 cuboctahedra. In the second Ga site, Ga(2) is bonded to four equivalent Tc(1) and eight equivalent Ga(1) atoms to form GaGa8Tc4 cuboctahedra that share corners with four equivalent Ga(2)Ga8Tc4 cuboctahedra, corners with eight equivalent Tc(1)Ga12 cuboctahedra, edges with eight equivalent Ga(2)Ga8Tc4 cuboctahedra, edges with sixteen equivalent Ga(1)Ga8Tc4 cuboctahedra, faces with four equivalent Ga(2)Ga8Tc4 cuboctahedra, faces with six equivalent Tc(1)Ga12 cuboctahedra, and faces with eight equivalent Ga(1)Ga8Tc4 cuboctahedra. is represented by the CIF file [CIF]
