我们提出了第一个Imma钙钛矿型氮氧化物的例子。研究发现，LaTiO₂N具有Imma钙钛矿型结构，并具有⁰b⁻b - tilt系统。Ti - （O，N）共价键和N原子的存在是导致LaTiO₂N光催化剂带隙减小的原因。
We present the first example of Imma perovskite-type oxynitride. LaTiO₂N was found to have an Imma perovskite-type structure with a⁰b⁻b⁻ tilt system. The Ti–(O,N) covalent bonding and existence of N atoms are responsible for the reduced band gap of LaTiO₂N photocatalyst.
