Abstract: In the title one-dimensional coordination polymer {systematic name: catena-poly[[[aqua(1,10-phenanthroline-²N,N')copper(II)]--phenylenebis(oxyacetato)-²O:O'] dihydrate]}, {[Cu(C₁₀H₈O₆)(C₁₂H₈N₂)(H₂O)]·2H₂O}_n, the Cu^II atom has a distorted square-pyramidal coordination geometry, defined by two carboxyl O-atom donors from two benzene-1,3-dioxyacetate groups, two N-atom donors from the 1,10-phenanthroline ligand and one water molecule. The Cu^II ions are bridged by benzene-1,3-dioxyacetate dianions (1,3-BDOA^2-), resulting in a one-dimensional chain structure. The intrachain CuCu separation is 9.769 (4) Å. The chains are linked into a three-dimensional supramolecular network via hydrogen bonds and - stacking interactions.
