ZrTcNiCd crystallizes in the trigonal R3m space group. Zr(1) is bonded in a 10-coordinate geometry to four equivalent Tc(1), three equivalent Ni(1), and three equivalent Cd(1) atoms. There is one shorter (2.63 Å) and three longer (2.86 Å) Zr(1)-Tc(1) bond lengths. All Zr(1)-Ni(1) bond lengths are 2.70 Å. All Zr(1)-Cd(1) bond lengths are 2.70 Å. Tc(1) is bonded in a 2-coordinate geometry to four equivalent Zr(1), one Ni(1), and three equivalent Cd(1) atoms. The Tc(1)-Ni(1) bond length is 1.66 Å. All Tc(1)-Cd(1) bond lengths are 2.70 Å. Ni(1) is bonded in a 5-coordinate geometry to three equivalent Zr(1), one Tc(1), and four equivalent Cd(1) atoms. There is one shorter (2.63 Å) and three longer (2.86 Å) Ni(1)-Cd(1) bond lengths. Cd(1) is bonded in a 10-coordinate geometry to three equivalent Zr(1), three equivalent Tc(1), and four equivalent Ni(1) atoms.
