Abstract: In the title one-dimensional coordination polymer, [Cu(tdzdta)(phen)(H₂O)]_n [where tdzdta^2- is the 1,3,4-thiadiazole-2,5-diyldithiodiacetate dianion (C₆H₄N₂O₄S₃^2-) and phen is 1,10-phenanthroline (C₁₂H₈N₂)], the Cu^II atom displays an elongated square-pyramidal coordination geometry with the base capped by one very long semicoordinate Cu-O_carboxylate bond [2.842 (2) Å]. The Cu^II ions are bridged by tdzdta^2- groups, resulting in a one-dimensional chain structure. The intrachain CuCu separation is 9.112 (4) Å. Furthermore, the chains are linked into a three-dimensional supramolecular network via hydrogen bonds and - stacking interactions.
