In the hydro-thermally prepared title coordination polymer, Ni(C(2)H(6)NO(3)S)(2)(C(12)H(10)N(4)), the Ni(II) ion and the 1,4-bis-(1H-imidazol-1-yl)benzene ligand occupy special positions on inversion centers. The metal ion shows a slightly distorted octa-hedral coordination geometry, being linked to two N atoms of two 1,4-bis-(imidazol-1-yl)benzene ligands and to two O and two N atoms of two chelating 2-amino-ethane-sulfonate ligands. The 1,4-bis-(imidazol-1-yl)benzene ligands bridge symmetry-related Ni(II) ions forming polymeric chains along the [110] direction.
在水热法制备的标题配位聚合物[Ni(C₂H₆NO₃S)₂(C₁₂H₁₀N₄)]ₙ中，Ni(II)离子和1,4-双(1H-咪唑-1-基)苯配体占据反演中心的特殊位置。金属离子呈现出略微扭曲的八面体配位几何构型，与两个1,4-双(咪唑-1-基)苯配体的两个N原子以及两个螯合的2-氨基乙磺酸盐配体的两个O原子和两个N原子相连。1,4-双(咪唑-1-基)苯配体桥连对称相关的Ni(II)离子，沿[110]方向形成聚合物链。
