Addition of in situ generated hydroxymethylacetylenide (terminal C‐deprotonated propargylic alcohol, prop‐2‐yn‐1‐ol, C₃H₃OH) to aqueous solutions of AgNO₃ in 1:1 molar ratio results in the formation of two new coordination polymers, {AgNO₃·2[Ag(C₃H₂OH)]·²/₃H₂O}_∞ (1) and {AgNO₃·3Ag(C₃H₂OH)}_∞ (2). Storage of crystalline samples of 1 or 2 under mother liquor at 5 °C for two weeks results in a new crystalline phase, {AgNO₃·2[Ag(C₃H₂OH)]·H₂O}_∞ (3). Another two weeks evolution yields {AgNO₃·2Ag(C₃H₂OH)}_∞ (4). This product can be prepared in high scale by changing the reagent ratio between the hydroxymethylacetylenide and AgNO₃ to 0.5:1. All products are colorless crystalline materials, and their structures were determined by single‐crystal X‐ray diffraction. They are highly light sensitive, in particular, in the presence of trace amounts of impurities.

银羟基甲基乙炔配位聚合物的化学计量和结构多样性

在1：1摩尔比的AgNO ₃水溶液中添加原位生成的羟甲基乙炔（末端C-去质子化的炔丙醇，prop-2-yn-1-ol，C ₃ H ₃ OH）导致形成两个新的配位基聚合物{AgNO ₃ · 2 [Ag（C ₃ H ₂ OH）] · ² / ₃ H ₂ O} _∞（1）和{AgNO ₃ · 3Ag（C ₃ H ₂ OH）} _∞（2）。储存1或2个晶体样品在母液中于5°C下放置两周会产生新的结晶相{AgNO ₃ · 2 [Ag（C ₃ H ₂ OH）] · H ₂ O} _∞（3）。另外两周的演化产生{AgNO ₃ · 2Ag（C ₃ H ₂ OH）} _∞（4）。通过改变羟甲基乙炔与AgNO ₃之间的试剂比例，可以大规模制备该产品到0.5：1。所有产品均为无色晶体材料，其结构通过单晶X射线衍射确定。它们对光非常敏感，特别是在存在痕量杂质的情况下。
