The crystal structure described by NaMnAs 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. Mn(1) is bonded to four equivalent As(1) atoms to form a mixture of distorted corner and edge-sharing MnAs4 tetrahedra. As(1) is bonded in a 9-coordinate geometry to five equivalent Na(1) and four equivalent Mn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
