Synthetic Route of Layered Titanium Nitride Chloride TiNCl Using Sodium Amide

[Image: see text] A synthetic route in a closed system for layered titanium nitride chloride TiNCl has been developed using sodium amide NaNH(2) as a nitrogen source. A highly crystalline sample is obtained by an appropriate thermal decomposition of aminated titanium chloride. The obtained TiNCl was...

description [Image: see text] A synthetic route in a closed system for layered titanium nitride chloride TiNCl has been developed using sodium amide NaNH(2) as a nitrogen source. A highly crystalline sample is obtained by an appropriate thermal decomposition of aminated titanium chloride. The obtained TiNCl was also characterized using electronic resistivity measurement and photoemission spectroscopy. TiNCl showed hopping conduction compatible with an in-gap state revealed by photoelectron spectroscopy. However, it appeared highly electron-doped, albeit without showing superconductivity. Comparison with the spectrum of superconducting sodium-doped samples suggests the presence of the microstructure required to exhibit superconductivity.
