The title compound, [Ni(C(2)H(8)N(2))(C(6)H(18)N(4))]S(2)O(3)·3H(2)O, was accidentally synthesized under solvothermal conditions applying [Ni(en)(3)]Cl(2) (en is ethane-1,2-diamine) as the Ni source. The asymmetric unit consists of one discrete Ni(tren)(en) complex [tren is N,N-bis-(2-amino-eth-yl)ethane-1,2-diamine] in which the Ni(2+) cation is sixfold coord-inated within a slightly distorted octa-hedron, one thio-sulfate anion and three water mol-ecules. In the crystal, the complex cations, anions and water mol-ecules are linked by an intricate hydrogen-bonding network. One C atom of the tren ligand, as well as one O atom of a water mol-ecule, are disordered over two sites and were refined using a split model (occupancy ratios = 0.85:15 and 0.60:0.40, respectively).
标题化合物[Ni(C₂H₈N₂)(C₆H₁₈N₄)]S₂O₃·3H₂O是在溶剂热条件下，以[Ni(en)₃]Cl₂（en为乙二胺）作为镍源意外合成得到的。不对称单元由一个离散的[Ni(tren)(en)]²⁺配合物（tren为N,N-双(2-氨基乙基)乙二胺）组成，其中Ni²⁺阳离子在一个轻微扭曲的八面体中呈六配位，一个硫代硫酸根阴离子和三个水分子。在晶体中，配合物阳离子、阴离子和水分子通过复杂的氢键网络相连。tren配体的一个C原子以及一个水分子的一个O原子在两个位置上无序，采用分裂模型进行精修（占有率分别为0.85:0.15和0.60:0.40）。
