Materials Data on CeCuSO by Materials Project

Abstract

CeCuOS 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 S2- and four equivalent O2- atoms. All Ce–S bond lengths are 3.18 Å. All Ce–O bond lengths are 2.33 Å. Cu1+ is bonded to four equivalent S2- atoms to form a mixture of edge and corner-sharing CuS4 tetrahedra. All Cu–S bond lengths are 2.41 Å. S2- is bonded in a 4-coordinate geometry to four equivalent Ce3+ and four equivalent Cu1+ atoms. O2- is bonded to four equivalent Ce3+ atoms to form a mixture of edge and corner-sharing OCe4 tetrahedra.
