In the linear coordination polymer catena ‐poly[[[aqua(1,10‐phenanthroline‐κ 2 N , N ′)copper(II)]‐μ‐pyridine‐2,6‐dicarboxylato‐κ 4 O 2 : O 2′ , N , O 6 ‐[(nitrato‐κ 2 O , O ′)bismuth(III)]‐μ‐pyridine‐2,6‐dicarboxylato‐κ 4 O 2 , N , O 6 : O 6′ ] dihydrate], {[Bi III Cu II (C 7 H 3 NO 4 ) 2 (NO 3 )(C 12 H 8 N 2 )(H 2 O)]·2H 2 O} n , the Bi III cation is O , N , O ′‐chelated by the two pyridine‐2,6‐dicarboxylate ligands and O , O ′‐chelated by the nitrate anion, the nine coordinating atoms conferring a tricapped trigonal prismatic environment on the metal centre. Each pyridine‐2,6‐dicarboxylate ligand uses one of its carboxylate O atoms to bind to an aqua(1,10‐phenanthroline)copper(II) unit, the Cu—O dative bonds giving rise to the formation of a ribbon motif. The Cu II cation exhibits a square‐pyramidal geometry. The ribbon motif propagates along the shortest axis of the triclinic unit cell and the solvent water molecules are hydrogen bonded to the same ribbon.
