HfTc2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. Hf(1) is bonded in a 12-coordinate geometry to three equivalent Tc(1) and nine equivalent Tc(2) atoms. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded to six equivalent Hf(1) and six equivalent Tc(2) atoms to form a mixture of edge, corner, and face-sharing TcHf6Tc6 cuboctahedra. In the second Tc site, Tc(2) is bonded to six equivalent Hf(1), two equivalent Tc(1), and four equivalent Tc(2) atoms to form a mixture of edge, corner, and face-sharing TcHf6Tc6 cuboctahedra.
HfTc2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. Hf(1) is bonded in a 12-coordinate geometry to three equivalent Tc(1) and nine equivalent Tc(2) atoms. All Hf(1)-Tc(1) bond lengths are 3.04 Å. There are six shorter (3.05 Å) and three longer (3.06 Å) Hf(1)-Tc(2) bond lengths. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded to six equivalent Hf(1) and six equivalent Tc(2) atoms to form a mixture of edge, corner, and face-sharing TcHf6Tc6 cuboctahedra. All Tc(1)-Tc(2) bond lengths are 2.66 Å. In the second Tc site, Tc(2) is bonded to six equivalent Hf(1), two equivalent Tc(1), and four equivalent Tc(2) atoms to form a mixture of edge, corner, and face-sharing TcHf6Tc6 cuboctahedra. There are two shorter (2.50 Å) and two longer (2.68 Å) Tc(2)-Tc(2) bond lengths.
