The crystal structure described by 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. is represented by the CIF card [CIF]
