Abstract: In the title complex, {[Cu(C₄H₅O₄N)(C₁₀H₉N₃)]·H₂O}_n, the Cu atom has a distorted CuO₂N₃ square-pyramidal geometry formed by an N,O-bidentate aspartate (asp) anion and an N,N-bidentate 2,2'-bipyridylamine (bpa) molecule in the basal positions, and an O-monodentate asp ligand in the apical site. The complex forms a polymeric chain in which each metal centre is bridged to the next one by the asp anion. The crystal structure is stabilized by O-HO and N-HO hydrogen bonds and - stacking interactions involving the bpa ligands [centroid-centroid separation = 3.699 (4) Å].
