The title compound, [Ni(C2H8N2)(C6H18N4)]S2O3·3H2O, was accidentally synthesized under solvothermal conditions applying [Ni(en)3]Cl2 (en is ethane-1,2-diamine) as the Ni source. The asymmetric unit consists of one discrete [Ni(tren)(en)]2+ complex [tren is N,N-bis(2-aminoethyl)ethane-1,2-diamine] in which the Ni2+ cation is sixfold coordinated within a slightly distorted octahedron, one thiosulfate anion and three water molecules. In the crystal, the complex cations, anions and water molecules are linked by an intricate hydrogen-bonding network. One C atom of the tren ligand, as well as one O atom of a water molecule, are disordered over two sites and were refined using a split model (occupancy ratios = 0.85:15 and 0.60:0.40, respectively).
