Materials Data on PrZnSbO by Materials Project

Abstract

PrOZnSb is Parent of FeAs superconductors structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Pr3+ is bonded in a 4-coordinate geometry to four equivalent Sb3- and four equivalent O2- atoms. All Pr–Sb bond lengths are 3.55 Å. All Pr–O bond lengths are 2.39 Å. Zn2+ is bonded to four equivalent Sb3- atoms to form a mixture of edge and corner-sharing ZnSb4 tetrahedra. All Zn–Sb bond lengths are 2.74 Å. Sb3- is bonded in a 8-coordinate geometry to four equivalent Pr3+ and four equivalent Zn2+ atoms. O2- is bonded to four equivalent Pr3+ atoms to form a mixture of distorted edge and corner-sharing OPr4 tetrahedra.
