Abstract

In the title compound, (C(4)H(14)N(2))[Cd(C(7)H(3)NO(4))(2)]·2H(2)O, 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-dicarboxyl-ato ligands in a distorted octa-hedral geometry. The uncoordinated water mol-ecules are involved in O-H⋯O and N-H⋯O hydrogen bonds, which contribute to the formation of a three-dimensional supra-molecular structure, along with π-π stacking inter-actions [centroid-centroid distances of 3.5313 (13) and 3.6028 (11) Å between the pyridine rings of neighbouring dianions].
