Addition of in situ generated hydroxymethylacetylenide (terminal C‐deprotonated propargylic alcohol, prop‐2‐yn‐1‐ol, C 3 H 3 OH) to aqueous solutions of AgNO 3 in 1:1 molar ratio results in the formation of two new coordination polymers, {AgNO 3 · 2[Ag(C 3 H 2 OH)] · 2 / 3 H 2 O} ∞ ( 1 ) and {AgNO 3 · 3Ag(C 3 H 2 OH)} ∞ ( 2 ). Storage of crystalline samples of 1 or 2 under mother liquor at 5 °C for two weeks results in a new crystalline phase, {AgNO 3 · 2[Ag(C 3 H 2 OH)] · H 2 O} ∞ ( 3 ). Another two weeks evolution yields {AgNO 3 · 2Ag(C 3 H 2 OH)} ∞ ( 4 ). This product can be prepared in high scale by changing the reagent ratio between the hydroxymethylacetylenide and AgNO 3 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.
