TaIrPdZn crystallizes in the trigonal R3m space group. Ta(1) is bonded in a distorted single-bond geometry to three equivalent Ir(1), three equivalent Pd(1), and one Zn(1) atom. All Ta(1)-Ir(1) bond lengths are 2.77 Å. All Ta(1)-Pd(1) bond lengths are 2.77 Å. The Ta(1)-Zn(1) bond length is 1.57 Å. Ir(1) is bonded in a 7-coordinate geometry to three equivalent Ta(1), one Pd(1), and three equivalent Zn(1) atoms. The Ir(1)-Pd(1) bond length is 1.57 Å. All Ir(1)-Zn(1) bond lengths are 2.77 Å. Pd(1) is bonded in a 8-coordinate geometry to three equivalent Ta(1), one Ir(1), and four equivalent Zn(1) atoms. There are three shorter (2.62 Å) and one longer (3.09 Å) Pd(1)-Zn(1) bond length. Zn(1) is bonded in a distorted single-bond geometry to one Ta(1), three equivalent Ir(1), and four equivalent Pd(1) atoms.
