Imma perovskite-type oxynitride LaTiO2N: structure and electron density.
We present the first example of Imma perovskite-type oxynitride. LaTiO(2)N was found to have an Imma perovskite-type structure with a(0)b(-)b(-) tilt system. The Ti-(O,N) covalent bonding and existence of N atoms are responsible for the reduced band gap of LaTiO(2)N photocatalyst.
