The compound described by Tc3Ni is Magnesium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. Tc(1) is bonded to eight equivalent Tc(1) and four equivalent Ni(1) atoms to form TcTc8Ni4 cuboctahedra that share corners with four equivalent Ni(1)Tc12 cuboctahedra, corners with fourteen equivalent Tc(1)Tc8Ni4 cuboctahedra, edges with six equivalent Ni(1)Tc12 cuboctahedra, edges with twelve equivalent Tc(1)Tc8Ni4 cuboctahedra, faces with four equivalent Ni(1)Tc12 cuboctahedra, and faces with sixteen equivalent Tc(1)Tc8Ni4 cuboctahedra. Ni(1) is bonded to twelve equivalent Tc(1) atoms to form NiTc12 cuboctahedra that share corners with six equivalent Ni(1)Tc12 cuboctahedra, corners with twelve equivalent Tc(1)Tc8Ni4 cuboctahedra, edges with eighteen equivalent Tc(1)Tc8Ni4 cuboctahedra, faces with eight equivalent Ni(1)Tc12 cuboctahedra, and faces with twelve equivalent Tc(1)Tc8Ni4 cuboctahedra. is represented by the CIF card [CIF]
