Materials Data on PrCuSO by Materials Project
(PrO)CuS is Parent of FeAs superconductors structured and crystallizes in the tetragonal P4/nmm space group. The structure is two-dimensional and consists of one CuS sheet oriented in the (0, 0, 1) direction and one PrO sheet oriented in the (0, 0, 1) direction. In the CuS sheet, 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 2.42 Å. S2- is bonded in a 4-coordinate geometry to four equivalent Cu1+ atoms. In the PrO sheet, Pr3+ is bonded in a 4-coordinate geometry to four equivalent O2- atoms. All Pr–O bond lengths are 2.35 Å. O2- is bonded to four equivalent Pr3+ atoms to form a mixture of edge and corner-sharing OPr4 tetrahedra.
