Description:Literature Seminar:\n\nOxynitrides and their ability to be synt
 hesized are an important facet in the solid-state chemistry field. Their p
 roperties are more tunable than in their single-anion counterparts as anio
 ns exhibit different characteristics (i.e. electronegativity) that contrib
 ute to the overall properties of the material. However\, difficulty in the
 ir synthesis arises due to the intrinsic stability of nitrogen. The curren
 t technique to make these materials requires high-temperature (800-1300°C
 ) ammonolysis (treatment with NH3). However\, this technique involves a hi
 ghly reducing atmosphere and N3- has low ability to incorporate into the l
 attice due to its large charge. The idea of a labile ligand as seen in coo
 rdination chemistry is extended in the solid-state to exchange the labile 
 hydride in BaTiO3-xHx for nitrogen to make BaTiO3-xN2x/3 (an oxynitride). 
 The H- ion can be exchanged with N3- through low temperature (&lt\;500°C)
  treatment with NH3. In this talk\, I will discuss why this exchange occur
 s and what characterization techniques were done to prove this exchange. T
 he extension of this low-temperature hydride technique to other systems wi
 ll also be discussed.\n\nYajima\, T.\; Takeiri\, F.\; Aidzu\, K.\; Akamats
