catena‐Poly[[[(pyridine‐κN)copper(II)]‐μ‐N‐(3‐carboxy­salicylidene)glycinato‐κ4N,O,O′:O′] monohydrate]

In the polymeric title compound, {[Cu(C10H7NO5)(C5H5N)]·H2O}n, the Cu atom adopts square-based pyramidal coordination involving the tridentate N,O,O′-chelated dianionic ligand, a pyridine N atom and an apical, bridging, carboxyl­ate O atom from an adjacent ligand. This results in helical chains propagating along the b axis of the monoclinic unit cell.
