Sr Zr Nb Pd
SrZrNbPd crystallizes in the trigonal R3m space group. Sr(1) is bonded in a 1-coordinate geometry to four equivalent Zr(1), one Nb(1), and six equivalent Pd(1) atoms. There are three shorter (2.96 Å) and one longer (3.17 Å) Sr(1)-Zr(1) bond length. The Sr(1)-Nb(1) bond length is 2.51 Å. There are three shorter (3.29 Å) and three longer (3.68 Å) Sr(1)-Pd(1) bond lengths. Zr(1) is bonded in a 8-coordinate geometry to four equivalent Sr(1) and four equivalent Pd(1) atoms. There are three shorter (2.96 Å) and one longer (3.17 Å) Zr(1)-Pd(1) bond length. Nb(1) is bonded in a 1-coordinate geometry to one Sr(1) and four equivalent Pd(1) atoms. There are three shorter (2.96 Å) and one longer (3.17 Å) Nb(1)-Pd(1) bond length. Pd(1) is bonded in a 14-coordinate geometry to six equivalent Sr(1), four equivalent Zr(1), and four equivalent Nb(1) atoms.
