The material structure described by GdTc3 is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm space group. Gd(1) is bonded in a distorted body-centered cubic geometry to six equivalent Tc(2) and eight equivalent Tc(1) atoms. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded to four equivalent Gd(1) and four equivalent Tc(2) atoms to form a mixture of distorted face, corner, and edge-sharing TcGd4Tc4 tetrahedra. In the second Tc site, Tc(2) is bonded in a 14-coordinate geometry to six equivalent Gd(1) and eight equivalent Tc(1) atoms. is represented by the CIF card [CIF]
