Tetraaqua(7-hydroxy-5-oxidoflavone-6-sulfonato-kappa2O4,O5)nickel(II) dimethylformamide solvate monohydrate.

In the title compound, [Ni(C15H8O7S)(H2O)4].C3H7NO.H2O, the NiII cation is chelated by a 7-hydroxy-5-oxidoflavone-6-sulfonate ligand through one oxide and one carbonyl O atom, and the sixfold coordination is completed by four aqua ligands. Individual molecules are linked into hydrogen-bonded dimers by way of five pairs of O-H...O hydrogen bonds. These dimers, in turn, determine a three-dimensional supramolecular arrangement through a variety of interdimeric interactions, such as O-H...O, C-H...O and pi-pi stacking.
