配位聚合物[Cu（H_2O）_2（μ_2-NC）_4PtX_2]（X = Cl，Br）通过弱的X···X相互作用形成正方形网格片的网络结构。在逐步脱水后，这些层融合，形成扭曲立方体的3D网络。测试了材料对二甲基亚砜、N，N-二甲基甲酰胺和吡啶的可见蒸气变色、拉曼和IR响应。分析物结合的配位聚合物的形式Cu（分析物）2[PtX 2（CN）4]的结构特征通过PXRD，并发现形成层的正方形网格，通过X···X相互作用对齐。[Cu（H2O）2（μ2-NC）4PtX 2]与浓NH3水溶液反应生成[PtBr（CN）4（NH3）]-和[PtCl（CN）4（OH）]2-阴离子，并将其纳入一维链状结构。紫外-可见光反射数据表明，[Cu（H2O）2（μ2-NC）4PtBr 2]的d-d跃迁和可见Br-Pt LMCT吸收带的结合导致了比含氯类似物更大的汽致变色效应。
The coordination polymers [Cu(H2O)2(μ2-NC)4PtX2] (X = Cl, Br) form networks of square grid sheets that align in a staggered manner with one another via weak X···X interactions. Upon stepwise dehydration, the layers fuse, forming a 3-D network of distorted cubes. The materials were tested for visible vapochromic, Raman, and IR response to dimethyl sulfoxide, N,N-dimethylformamide, and pyridine. Analyte-bound coordination polymers of the form Cu(analyte)2[PtX2(CN)4] were structurally characterized by PXRD and found to form layers of square grids that align through X···X interactions. The reaction of [Cu(H2O)2(μ2-NC)4PtX2] with concentrated aqueous NH3 generated [PtBr(CN)4(NH3)]- and [PtCl(CN)4(OH)]2- anions that were incorporated into 1-D chain structures. UV-visible reflectance data show that a combination of shifting d-d transitions and the visible Br-Pt LMCT absorption band in [Cu(H2O)2(μ2-NC)4PtBr2] results in a greater vapochromic effect in comparison to that in chlorine-containing analogues.
