摘要

通过软还原 NbI4 制备了富含金属的氧碘化铌。新化合物 Nb4OI10 的结构是通过单晶 X 射线衍射测定的，其中包含一个矩形 Nb4(μ4-O) 簇，该簇通过碘配体相互连接成层。Nb4OI10 簇的局部结构与有缺陷的 Nb6I11 结构关系密切。二维范德华材料 Nb4OI8I4/2] 是一种小带隙半导体（<1 eV），通过电导率测量、光响应、实验带隙测定和带结构计算进行了分析。

The Rectangular Niobium Oxyiodide Cluster Nb4OI10 – A Narrow Band-Gap Semiconductor

A metal-rich niobium oxyiodide was prepared by soft reduction of NbI₄. The structure of the new compound Nb₄OI₁₀ was determined by single-crystal X-ray diffraction and contains a rectangular Nb₄(μ₄-O) cluster that is interconnected into layers by iodide ligands. The local structure of the Nb₄OI₁₀ cluster bears a close relationship to a defect Nb₆I₁₁ structure. The two-dimensional van der Waals material Nb₄OI₈I_4/2] is a small band-gap semiconductor (<1 eV), as analysed by electrical conductivity measurements, photoresponse, experimental band gap determination, and band structure calculation.
