Materials Data on CeZnSbO by Materials Project

Abstract

CeZnSbO is Parent of FeAs superconductors structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Ce3+ is bonded in a 4-coordinate geometry to four equivalent Sb3- and four equivalent O2- atoms. All Ce–Sb bond lengths are 3.47 Å. All Ce–O bond lengths are 2.38 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 2.75 Å. Sb3- is bonded in a 8-coordinate geometry to four equivalent Ce3+ and four equivalent Zn2+ atoms. O2- is bonded to four equivalent Ce3+ atoms to form a mixture of edge and corner-sharing OCe4 tetrahedra.
