The title compound, {[Ni(SO4)(C6H16N2)(H2O)2]·H2O} n , contains a Ni(II) atom that is coordinated nearly octa-hedrally by a chelating tetra-ethyl-enediamine (tmeda) ligand, two water mol-ecules in a cis arrangement and two O atoms of two sulfate anions in a trans arrangement. The sulfate anions act as μ2-bridging ligands leading to a chain structure of alternating NiO4N2 octa-hedra and SO4 tetra-hedra parallel to [001]. The polymeric chains are linked by O-H⋯O hydrogen bonds between coordinating water mol-ecules and sulfate anions to give double strands. There is a lattice water mol-ecule which is also involved in O-H⋯O hydrogen bonding between adjacent [Ni(SO4)(tmeda)(H2O)2] chains.
标题化合物{[Ni(SO₄)(C₆H₁₆N₂)(H₂O)₂]·H₂O}ₙ包含一个Ni(II)原子,该原子由螯合的四乙二胺(tmeda)配体、两个呈顺式排列的水分子以及两个呈反式排列的硫酸根阴离子的两个O原子近似八面体配位。硫酸根阴离子作为μ₂-桥联配体,导致形成平行于[001]的由交替的NiO₄N₂八面体和SO₄四面体组成的链状结构。聚合物链通过配位水分子与硫酸根阴离子之间的O—H⋯O氢键相连形成双链。存在一个晶格水分子,它也参与相邻[Ni(SO₄)(tmeda)(H₂O)₂]链之间的O—H⋯O氢键作用。
