Bis[[aqua­(1H-imidazo[4,5-f][1,10]phenanthroline-κ²N⁶,N⁷)cadmium]bis­(μ-pyridine-2,3-dicarboxyl­ato)-κ³N,O²:O³;κ³O³:N,O²]

In the title compound, [Cd₂(C₇H₃NO₄)₂(C₁₃H₈N₄)₂(H₂O)₂], the Cd^II ion is six-coordinated by two N atoms from a 1H-imidazo[4,5-f][1,10]phenanthroline (IP) ligand, one N atom and one O atom from a pyridine-2,3-dicarboxyl­ate (pdc) ligand, one O atom from another pdc ligand and one water mol­ecule in a distorted octa­hedral geometry. Two Cd^II ions are bridged by a pair of pdc ligands, forming a centrosymmetric dinuclear structure. Neighboring dinuclear units are linked by the coordinated water mol­ecules through O—H...N and O—H...O hydrogen bonds, forming a layer parallel to (011). The layers are further linked into a three-dimensional network through N—H...O hydrogen bonds. π–π inter­actions between the IP ligands further stabilize the supra­molecular structure [centroid–centroid distances = 3.579 (3), 3.686 (3), 3.710 (3), 3.766 (3) and 3.841 (3) Å].
