LaFePO 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 P(1) and four equivalent O(1) atoms. Fe(1) is bonded to four equivalent P(1) atoms to form a mixture of corner and edge-sharing FeP4 tetrahedra. P(1) is bonded in a 8-coordinate geometry to four equivalent La(1) and four equivalent Fe(1) atoms. O(1) is bonded to four equivalent La(1) atoms to form a mixture of corner and edge-sharing OLa4 tetrahedra.
