Zr Ta Cu Pd
ZrTaPdCu crystallizes in the trigonal R3m space group. Zr(1) is bonded in a 10-coordinate geometry to three equivalent Ta(1), four equivalent Pd(1), and three equivalent Cu(1) atoms. All Zr(1)-Ta(1) bond lengths are 2.70 Å. There is one shorter (2.74 Å) and three longer (2.83 Å) Zr(1)-Pd(1) bond lengths. All Zr(1)-Cu(1) bond lengths are 2.70 Å. Ta(1) is bonded in a 10-coordinate geometry to three equivalent Zr(1), three equivalent Pd(1), and four equivalent Cu(1) atoms. All Ta(1)-Pd(1) bond lengths are 2.70 Å. There is one shorter (2.74 Å) and three longer (2.83 Å) Ta(1)-Cu(1) bond lengths. Pd(1) is bonded in a distorted single-bond geometry to four equivalent Zr(1), three equivalent Ta(1), and one Cu(1) atom. The Pd(1)-Cu(1) bond length is 1.50 Å. Cu(1) is bonded in a single-bond geometry to three equivalent Zr(1), four equivalent Ta(1), and one Pd(1) atom.
