The complex poly[[aqua(μ 2 ‐phthalato‐κ 2 O 1 : O 2 ){μ 3 ‐2‐[3‐(pyridin‐2‐yl)‐1 H ‐pyrazol‐1‐yl]acetato‐κ 4 N 2 , N 3 : O : O ′}{μ 2 ‐2‐[3‐(pyridin‐2‐yl)‐1 H ‐pyrazol‐1‐yl]acetato‐κ 3 N 2 , N 3 : O }dizinc(II)] dihydrate], {[Zn 2 (C 10 H 8 N 3 O 2 ) 2 (C 8 H 4 O 4 )(H 2 O)]·2H 2 O} n , has been prepared by solvothermal reaction of 2‐[3‐(pyridin‐2‐yl)‐1 H ‐pyrazol‐1‐yl]acetonitrile (PPAN) with zinc(II). Under hydrothermal conditions, PPAN is hydrolyzed to 2‐[3‐(pyridin‐2‐yl)‐1 H ‐pyrazol‐1‐yl]acetate (PPAA − ). The structure determination reveals that the complex is a one‐dimensional double chain containing cationic [Zn 4 (PPAA) 4 ] 4+ structural units, which are further extended by bridging phthalate ligands. The one‐dimensional chains are extended into a three‐dimensional supramolecular architecture via hydrogen‐bonding and π–π stacking interactions.
