TcPdSb2 is Copper structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two TcPdSb2 clusters. Tc(1) is bonded in a distorted single-bond geometry to one Pd(1) atom. The Tc(1)-Pd(1) bond length is 1.41 Å. Pd(1) is bonded in a 3-coordinate geometry to one Tc(1) and two equivalent Sb(1) atoms. Both Pd(1)-Sb(1) bond lengths are 0.98 Å. Sb(1) is bonded in a single-bond geometry to one Pd(1) atom.
