The title compound, [Zn(H2O)6][Zn(C7H4NO4)3]2, consists of two [Zn(py-2,3-dcH)3]- anions (py-2,3-dcH is 3-carboxypyridine-2-carboxylate) and one [Zn(H2O)6]2+ cation. The anion is a six-coordinate complex located on a threefold rotation axis with a slightly distorted octahedral geometry around Zn2+ ion. The cation is also six-coordinate with an octahedral geometry around the Zn atom, located at a inverse threefold axis. Non-covalent interactions such as π-π stacking [centroid-centroid distance = 3.828(4)Å] and O-H...O hydrogen bonds play important roles in stabilizing the supramolecular structure.

Nyckelord: X-ray diffraction, coordination, zinc-complex
