Abstract

SrZnBi2 is Parent of FeAs superconductors-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are three inequivalent Sr sites. In the first Sr site, Sr is bonded to four Zn and eight Bi atoms to form distorted SrZn4Bi8 cuboctahedra that share corners with eight equivalent SrZn4Bi8 cuboctahedra, corners with eight ZnSr4Bi4 tetrahedra, edges with four equivalent SrZn4Bi8 cuboctahedra, edges with four ZnSr4Bi4 tetrahedra, and faces with five equivalent SrZn4Bi8 cuboctahedra. All Sr–Zn bond lengths are 3.73 Å. There are four shorter (3.47 Å) and four longer (3.59 Å) Sr–Bi bond lengths. In the second Sr site, Sr is bonded to four Zn and eight Bi atoms to form distorted SrZn4Bi8 cuboctahedra that share corners with eight SrZn4Bi8 cuboctahedra, corners with eight ZnSr4Bi4 tetrahedra, edges with four equivalent SrZn4Bi8 cuboctahedra, edges with four ZnSr4Bi4 tetrahedra, and faces with five SrZn4Bi8 cuboctahedra. All Sr–Zn bond lengths are 3.73 Å. There are four shorter (3.47 Å) and four longer (3.59 Å) Sr–Bi bond lengths.
