Formation of As-As Interlayer Bonding in the collapsed tetragonal phase of NaFe(2)As(2) under pressure

NaFe(2)As(2) is investigated experimentally using powder x-ray diffraction and Raman spectroscopy at pressures up to 23 GPa at room temperature and using ab-initio calculations. The results reveal a pressure-induced structural modification at 4 GPa from the starting tetragonal to a collapsed tetrago...
