An organic-inorganic hybrid silver iodobismuthate characteristic of the infrequent [AgBiIL] cluster (L = I or I) and with a unique Ag/Bi molar ratio (2/1), namely, [Zn(bipy)]AgBiI(I)(I) (bipy = 2,2'-bipyridine; 1), was solvothermally synthesized, and structurally, optically, and theoretically studied. Intriguingly, compound 1 exhibited semiconductor behavior with an optical band gap of 2.33 eV, which endowed it with excellent photoelectric and photocatalytic properties. Electronic structure calculations further revealed that the relative separate conduction band (CB) and valence band (VB) in compound 1 may be responsible for the good optical activity. This study also includes the Hirshfeld surface analyses, thermogravimetric measurements and X-ray photoelectron spectroscopy (XPS) characterization.
通过溶剂热法合成了一种有机-无机杂化碘铋酸银，其具有罕见的[AgBiIL]簇（L = I或I）且具有独特的Ag/Bi摩尔比（2/1），即[Zn(bipy)]AgBiI(I)(I)（bipy = 2,2'-联吡啶；1），并对其进行了结构、光学和理论研究。有趣的是，化合物1表现出半导体行为，其光学带隙为2.33 eV，这赋予了它优异的光电和光催化性能。电子结构计算进一步表明，化合物1中相对分离的导带（CB）和价带（VB）可能是其良好光学活性的原因。该研究还包括Hirshfeld表面分析、热重测量和X射线光电子能谱（XPS）表征。
