NdFeAsO is Parent of FeAs superconductors structured and crystallizes in the tetragonal P4/nmm space group. Nd(1) is bonded in a 4-coordinate geometry to four equivalent As(1) and four equivalent O(1) atoms. Fe(1) is bonded to four equivalent As(1) atoms to form a mixture of distorted corner and edge-sharing FeAs4 tetrahedra. As(1) is bonded in a 8-coordinate geometry to four equivalent Nd(1) and four equivalent Fe(1) atoms. O(1) is bonded to four equivalent Nd(1) atoms to form a mixture of corner and edge-sharing ONd4 tetrahedra.
