Deskripsi
The title compound, (C13H11N2)2[Ni(C7H3NO4)2]·3H2O, consists of a mononuclear anionic complex, two 9-aminoacridinium cations and three uncoordinated water molecules. Two pyridine-2,6-dicarboxylate (pydc) ligands are bound to the NiII ion, giving an NiN2O4 bonded set. The coordination geometry around the NiII atom is distorted octahedral. There are two types of robust O—H...O hydrogen-bond synthons, namely R66(24) and R24(8), which link the complex anions and water molecules to each other. N—H...O hydrogen bonds connect the stacks of anions and cations in the structure. Other intermolecular interactions, including weak C—H...O hydrogen bonds, π–π [shortest centroid–centroid distance = 3.336 (7) Å] and C—O...π [O...centroid distance = 3.562 (10) Å] interactions, connect the various components.
