两种碘银混合固体{[Ni（2，2 '-bipy）（THF）（2）（H2O）（2）]（Ag 10 I12）中心点2DMF}（n）（1）和{[Cu（2，2'-bipy）（3）]-（Ag-517）}（n）（2）（THF =四氢呋喃，DMF = N，N ′-二甲基甲酰胺，2，2 ′-联吡啶）在极性有机溶剂中合成，其一维碘代银酸盐聚合物由第二包埋的金属-有机络合物诱导。在1中，[Ag 5I 6]（n）（n-）链呈现出基于Ag 5I 6准五角星构建块的柱状结构。在2中，Z字形链[Ag 5I 7]（n）（2n-）由Ag 6 I11结构单元构成。两个化合物具有有趣的半导体性质，E-g = 2.74和2.80 eV。正如密度泛函理论计算所示，在I中观察到的强光致发光来自带边跃迁。
Two iodoargentate hybrid solids {[Ni(2,2'-bipy)(THF)(2)(H2O)(2)](Ag10I12)center dot 2DMF}(n) (1) and {[Cu(2,2'-bipy)(3)]-(Ag-517)}(n)(2) (THF = tetrahydrofuran, DMF = N,N'-dimethyl formamide, 2,2'-bipy = 2,2'-bipyridine) have been synthesized in a polar organic solvent, whose one-dimensional iodoargentate polymers are induced by second entrapped metal-organic complexes. In 1, the [Ag5I6](n)(n-) chain exhibits a columnar structure based on an Ag5I6 quasi-pentagram building block. In 2, the zigzag chain [Ag5I7](n)(2n-) is constructed from an Ag6I11 building block. Two compounds exhibit intriguing semiconducting properties with E-g = 2.74 and 2.80 eV. As indicated by density functional theory calculations, the observed strong photoluminescence in I arises from band-edge transitions.
