Li3Tc is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to four equivalent Li(1), four equivalent Li(2), and four equivalent Tc(1) atoms to form distorted LiLi8Tc4 cuboctahedra that share corners with twelve equivalent Li(1)Li8Tc4 cuboctahedra, edges with eight equivalent Li(1)Li8Tc4 cuboctahedra, edges with eight equivalent Tc(1)Li12 cuboctahedra, faces with four equivalent Tc(1)Li12 cuboctahedra, and faces with ten equivalent Li(1)Li8Tc4 cuboctahedra. In the second Li site, Li(2) is bonded in a square co-planar geometry to eight equivalent Li(1) and four equivalent Tc(1) atoms. Tc(1) is bonded to four equivalent Li(2) and eight equivalent Li(1) atoms to form TcLi12 cuboctahedra that share corners with four equivalent Tc(1)Li12 cuboctahedra, edges with eight equivalent Tc(1)Li12 cuboctahedra, edges with sixteen equivalent Li(1)Li8Tc4 cuboctahedra, faces with four equivalent Tc(1)Li12 cuboctahedra, and faces with eight equivalent Li(1)Li8Tc4 cuboctahedra.
