The material structure described by (LaO)CuS is Parent of FeAs superconductors structured and crystallizes in the tetragonal P4/nmm space group. La(1) is bonded in a 4-coordinate geometry to four equivalent S(1) and four equivalent O(1) atoms. Cu(1) is bonded to four equivalent S(1) atoms to form a mixture of corner and edge-sharing CuS4 tetrahedra. S(1) is bonded in a 8-coordinate geometry to four equivalent La(1) and four equivalent Cu(1) atoms. O(1) is bonded to four equivalent La(1) atoms to form a mixture of corner and edge-sharing OLa4 tetrahedra. is represented by the CIF file [CIF]
