title: Aqua-(benzene-1,2-dicarboxyl-ato-κO)bis-[2-(1H-pyrazol-3-yl-κN)pyridine-κN]cadmium(II).
abstract: In the mononuclear title complex, [Cd(C(8)H(4)O(4))(C(8)H(7)N(3))(2)(H(2)O)], the Cd(II) atom is six-coordinated in a distorted octa-hedral geometry by four N atoms from two bidentate chelating 2-(1H-pyrazol-3-yl)pyridine ligands, one O atom from a benzene-1,2-dicarboxyl-ate ligand and one water mol-ecule. The mol-ecular structure features intra-molecular O-H⋯O and N-H⋯O hydrogen bonds. In the crystal structure, the complex mol-ecules are assembled into a two-dimensional supra-molecular layer parallel to (011) via O-H⋯O and N-H⋯O hydrogen bonds and π-π stacking inter-actions between the pyridyl and pyrazole rings [centroid-centroid distances = 3.544 (2) and 3.722 (3) Å].
