Abstract: The title compound, [Cd(C₁₁H₅N₂O₂)₂(H₂O)₂], is a mononuclear complex consisting of a Cd^II atom, two 3-hydroxy-4,5-diazafluoren-9-one ligands and two coordinated water molecules. The Cd^II atom, lying on a twofold axis, displays a distorted octahedral coordintion. Adjacent molecules are linked by O-HO hydrogen bonds and - interactions [centroid-centroid distance = 3.84 (1) Å], leading to a one-dimensional chain. Weak C-HO hydrogen bonds connect the chains into a two-dimensional supramolecular structure.
