UTc3 crystallizes in the hexagonal P6_3/mmc space group. U(1) is bonded to twelve equivalent Tc(1) atoms to form a mixture of corner and face-sharing UTc12 cuboctahedra. Tc(1) is bonded in a 12-coordinate geometry to four equivalent U(1) and eight equivalent Tc(1) atoms.
UTc3 crystallizes in the hexagonal P6_3/mmc space group. U(1) is bonded to twelve equivalent Tc(1) atoms to form a mixture of corner and face-sharing UTc12 cuboctahedra. There are six shorter (2.71 Å) and six longer (3.00 Å) U(1)-Tc(1) bond lengths. Tc(1) is bonded in a 12-coordinate geometry to four equivalent U(1) and eight equivalent Tc(1) atoms. There are a spread of Tc(1)-Tc(1) bond distances ranging from 2.77-3.09 Å.
