The compound described by NaFeAs is Parent of FeAs superconductors-derived structured and crystallizes in the orthorhombic Cmcm space group. Na(1) is bonded in a 10-coordinate geometry to two equivalent Na(1), four equivalent Fe(1), and four equivalent As(1) atoms. Fe(1) is bonded to four equivalent Na(1) and four equivalent As(1) atoms to form a mixture of distorted face and edge-sharing FeNa4As4 tetrahedra. As(1) is bonded in a 8-coordinate geometry to four equivalent Na(1) and four equivalent Fe(1) atoms. is represented by the CIF file [CIF]
