Diaquabis(9-oxo-4,5-diazafluoren-3-olato-κ2N4,O3)cadmium(II)

Abstract

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