Materials Data on SmCuSeO by Materials Project
SmCuOSe is Parent of FeAs superconductors structured and crystallizes in the tetragonal P4/nmm space group. The structure is two-dimensional and consists of one CuSe sheet oriented in the (0, 0, 1) direction and one SmO sheet oriented in the (0, 0, 1) direction. In the CuSe sheet, Cu1+ is bonded to four equivalent Se2- atoms to form a mixture of edge and corner-sharing CuSe4 tetrahedra. All Cu–Se bond lengths are 2.52 Å. Se2- is bonded in a 12-coordinate geometry to four equivalent Cu1+ atoms. In the SmO sheet, Sm3+ is bonded in a 4-coordinate geometry to four equivalent O2- atoms. All Sm–O bond lengths are 2.31 Å. O2- is bonded to four equivalent Sm3+ atoms to form a mixture of edge and corner-sharing OSm4 tetrahedra.
