NaxHfNCl powder samples with average sodium content x av = 0, 0.18, 0.29, and 0.80 have been studied. The neutron powder diffraction patterns exhibit the phase separation in NaxHfNCl system except for x = 0 and 0.29. Obtained phases are a pristine phase β-HfNCl, a superconducting phase NaxHfNCl (Tc = 22-19 K) with narrow x-width (x = 0.28-0.29), a non-superconducting crystalline phase Na 0.9HfNCl, and a possible amorphous phase NaHfNCl.
