Abstract: The tetranuclear copper(II) title complex, [Cu₄Cl₂(OH)₄(C₁₀H₈N₂)₄](NO₃)₂·6H₂O, has a crystallographically imposed centre of symmetry. The metal atoms display a distorted tetragonal-pyramidal coordination geometry, and are linked by two ₂- and two ₃-hydroxo groups, assuming a chair-like conformation for the Cu₄O₂ core. In the crystal, the complex molecules are linked into a three-dimensional network by intermolecular O-HO, O-HCl, C-HO and C-HCl hydrogen bonds and - stacking interactions with centroid-centroid separations of 3.724 (2) and 3.767 (3) Å.
