NaFeAs is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Na(1) is bonded in a 5-coordinate geometry to five equivalent As(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 9-coordinate geometry to five equivalent Na(1) and four equivalent Fe(1) atoms.
NaFeAs is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Na(1) is bonded in a 5-coordinate geometry to five equivalent As(1) atoms. There are four shorter (2.94 Å) and one longer (3.14 Å) Na(1)-As(1) bond length. Fe(1) is bonded to four equivalent As(1) atoms to form a mixture of distorted corner and edge-sharing FeAs4 tetrahedra. All Fe(1)-As(1) bond lengths are 2.49 Å. As(1) is bonded in a 9-coordinate geometry to five equivalent Na(1) and four equivalent Fe(1) atoms.
