Aqua­(benzene-1,2-dicarboxyl­ato-κO)bis­[2-(1H-pyrazol-3-yl-κN 2)pyridine-κN]cadmium(II)

Abstract

In the mononuclear title complex, [Cd(C8H4O4)(C8H7N3)2(H2O)], the CdII atom is six-coordinated in a distorted octa­hedral geometry by four N atoms from two bidentate chelating 2-(1H-pyrazol-3-yl)pyridine ligands, one O atom from a benzene-1,2-dicarboxyl­ate ligand and one water mol­ecule. The mol­ecular structure features intra­molecular O—H⋯O and N—H⋯O hydrogen bonds. In the crystal structure, the complex mol­ecules are assembled into a two-dimensional supra­molecular layer parallel to (011) via O—H⋯O and N—H⋯O hydrogen bonds and π–π stacking inter­actions between the pyridyl and pyrazole rings [centroid–centroid distances = 3.544 (2) and 3.722 (3) Å]
