In the title coordination polymer, Cd(C(8)H(11)O(4))(2)(C(14)H(14)N(4)), the Cd atom (site symmetry 2) is six-coordin-ated by two O,O'-bidentate 4-carboxy-cyclo-hexa-necarboxyl-ate (Hchdc) ligands and two N atoms from two different 1,4-bis-(imidazol-1-ylmeth-yl)benzene (1,4-bix) mol-ecules in a very distorted cis-CdN(2)O(4) octa-hedral environment. The 1,4-bix mol-ecules act as bridging ligands that bind two Cd(II) atoms, thus forming an infinite chain propagating in [100], which is decorated by the Hchdc anions. The structure is completed by O-H⋯O hydrogen bonds, which link the chains together.
在标题配位聚合物[Cd(C₈H₁₁O₄)₂(C₁₄H₁₄N₄)]ₙ中,Cd原子(位点对称性2)在一个严重扭曲的顺式CdN₂O₄八面体环境中,由两个O,O'-双齿4-羧基环己烷羧酸酯(Hchdc)配体以及来自两个不同的1,4-双(咪唑-1-基甲基)苯(1,4-bix)分子的两个N原子进行六配位。1,4-bix分子作为桥连配体,连接两个Cd(II)原子,从而形成在[100]方向上延伸的无限链,Hchdc阴离子修饰该链。通过O—H⋯O氢键将这些链连接在一起,从而完善了结构。
