In the title coordination polymer, Fe(C(8)H(6)N(5)O(4))(2) {or FeL(2),where HL = 2-[(1H-1,2,4-triazol-1-yl) meth-yl]-1H-imidazole-4,5-dicarb-oxy-lic acid)}, the Fe(II) ion, located on an inversion centre, is six-coordinated by two O atoms and four N atoms from two L(-) ligands in a distorted octa-hedral geometry [Fe-O = 2.1452 (13), Fe-N = 2.1316 (14) and 2.2484 (15) Å]. There is an intra-molecular O-H⋯O hydrogen bond in each L(-) ligand. Being an effective tridentate bridging ligand, the deprotonated L(-) anions link two Fe(II) atoms, yielding a chain-like polymer propagating along [100]. In the crystal, these polymer chains are linked via N-H⋯N hydrogen bonds, forming a two-dimensional network.
在标题配位聚合物[Fe(C₈H₆N₅O₄)₂]ₙ{或[FeL₂]ₙ，其中HL = 2 - [(1H - 1,2,4 - 三唑 - 1 - 基)甲基] - 1H - 咪唑 - 4,5 - 二羧酸}中，位于对称中心的Fe(II)离子由来自两个L⁻配体的两个O原子和四个N原子以扭曲的八面体几何构型六配位[Fe - O = 2.1452(13)，Fe - N = 2.1316(14)和2.2484(15)Å]。每个L⁻配体中存在分子内O - H⋯O氢键。去质子化的L⁻阴离子作为有效的三齿桥连配体连接两个Fe(II)原子，形成沿[100]方向延伸的链状聚合物。在晶体中，这些聚合物链通过N - H⋯N氢键相连，形成二维网络。
