Abstract: The title complex, [Ni(C₂H₈N₂)₃](C₁₀H₆O₆S₂)·H₂O or [Ni(en)₃](2,6-nds)·H₂O (en = ethylenediamine and nds = naphthalene-2,6-disulfonate), contains one [Ni(en)₃]²⁺ cation, one water molecule, and two separate halves of centrosymmetric 2,6-nds^2- dianions in the asymmetric unit. The anions lie on inversion centres. A three-dimensional open framework is assembled by means of hydrogen-bonding interactions between the anions and the cations, in which there is a channel parallel to the c axis, with one of the 2,6-nds dianions occupying the channel.
