Materials Data on NdCuSO by Materials Project
(NdO)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 NdO 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 NdO sheet, Nd3+ is bonded in a 4-coordinate geometry to four equivalent O2- atoms. All Nd–O bond lengths are 2.32 Å. O2- is bonded to four equivalent Nd3+ atoms to form a mixture of edge and corner-sharing ONd4 tetrahedra.
