HfZrTcBi crystallizes in the trigonal R3m space group. Hf(1) is bonded in a 1-coordinate geometry to one Zr(1), four equivalent Tc(1), and three equivalent Bi(1) atoms. The Hf(1)-Zr(1) bond length is 1.96 Å. There are three shorter (2.89 Å) and one longer (3.32 Å) Hf(1)-Tc(1) bond length. All Hf(1)-Bi(1) bond lengths are 3.10 Å. Zr(1) is bonded in a 1-coordinate geometry to one Hf(1), three equivalent Tc(1), and four equivalent Bi(1) atoms. All Zr(1)-Tc(1) bond lengths are 3.10 Å. There are three shorter (2.89 Å) and one longer (3.32 Å) Zr(1)-Bi(1) bond length. Tc(1) is bonded in a 11-coordinate geometry to four equivalent Hf(1), three equivalent Zr(1), and four equivalent Bi(1) atoms. There are three shorter (2.89 Å) and one longer (3.32 Å) Tc(1)-Bi(1) bond length. Bi(1) is bonded in a 11-coordinate geometry to three equivalent Hf(1), four equivalent Zr(1), and four equivalent Tc(1) atoms.
