Abstract: In the title compound, (C₄H₁₄N₂)[Cd(C₇H₃NO₄)₂]·2H₂O, the Cd^II ion is coordinated by four O atoms [Cd-O = 2.2399 (17)-2.2493 (17) Å] and two N atoms [Cd-N = 2.3113 (15) and 2.3917 (15) Å] from two tridentate pyridine-2,6-dicarboxylato ligands in a distorted octahedral geometry. The uncoordinated water molecules are involved in O-HO and N-HO hydrogen bonds, which contribute to the formation of a three-dimensional supramolecular structure, along with - stacking interactions [centroid-centroid distances of 3.5313 (13) and 3.6028 (11) Å between the pyridine rings of neighbouring dianions].
