摘要

本文报道了氧化铅-碘化铅-碳二酰铅Pb8O4I6（CN2）的合成、晶体结构和电子性能。以PbI2、PbO和Pb（CN2）为原料，通过陶瓷法制备了n型半导体化合物，得到了一种空气稳定的深黄色晶体材料。单晶x射线衍射显示单斜空间群C2/c具有由碘化物桥和（NCN）2−单元连接的异立方型[Pb4O4]基序。通过漫反射紫外-可见光谱、莫特-肖特基分析和光致发光光谱对其光学性质进行了表征，从而对其电子结构进行了深入研究。

A mixed-anion compound based upon a [Pb4O4] heterocubane unit: synthesis, structure and electronic properties of Pb8O4I6(CN2)

The present study reports the synthesis, crystal structure, and electronic properties of the lead–oxide–iodide–carbodiimde Pb₈O₄I₆(CN₂). The n-type semiconducting compound was obtained via ceramic method from PbI₂, PbO and Pb(CN₂), yielding an air stable, dark yellow crystalline material. Single-crystal X-ray diffraction revealed the monoclinic space group C2/c featuring a heterocubane-type [Pb₄O₄] motif interconnected by iodide bridges and (NCN)²⁻ units. The optical properties were characterized by diffuse reflectance UV-Vis spectroscopy, Mott–Schottky analysis, and photoluminescence spectroscopy, providing insights into the electronic structure.
