Tc2PdBi crystallizes in the trigonal R3m space group. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a 7-coordinate geometry to one Tc(2), three equivalent Pd(1), and three equivalent Bi(1) atoms. The Tc(1)-Tc(2) bond length is 2.66 Å. All Tc(1)-Pd(1) bond lengths are 2.70 Å. All Tc(1)-Bi(1) bond lengths are 2.70 Å. In the second Tc site, Tc(2) is bonded in a single-bond geometry to one Tc(1), one Pd(1), and three equivalent Bi(1) atoms. The Tc(2)-Pd(1) bond length is 1.62 Å. All Tc(2)-Bi(1) bond lengths are 2.70 Å. Pd(1) is bonded in a single-bond geometry to one Tc(2), three equivalent Tc(1), and four equivalent Bi(1) atoms. There is one shorter (2.66 Å) and three longer (2.86 Å) Pd(1)-Bi(1) bond lengths. Bi(1) is bonded in a 10-coordinate geometry to three equivalent Tc(1), three equivalent Tc(2), and four equivalent Pd(1) atoms.
