In the crystal structure of the title compound, {[Cu(C(8)H(6)O(9))(C(12)H(8)N(2))]·0.69H(2)O}(n), the Cu(II) atom has a distorted octa-hedral geometry, coordinated by four O atoms from two 3,4-dicarboxy-tetra-hydro-furan-2,5-dicarboxyl-ate ligands and two N atoms from one 1,10-phenanthroline ligand. One of the carboxylate groups bridges the Cu(II) atoms, forming a zigzag chain running along the b axis. The chains are linked by a π-π inter-action between aromatic rings with a centroid-to-centroid distance of 3.567 (1) Å, and by hydrogen bonds between the carboxyl-ate group and the disordered water mol-ecule, forming a three-dimensional network.
在标题化合物{[Cu(C₈H₆O₉)(C₁₂H₈N₂)]·0.69H₂O}ₙ的晶体结构中,Cu(II)原子具有扭曲的八面体几何构型,由来自两个3,4 - 二羧基 - 四氢 - 呋喃 - 2,5 - 二羧酸盐配体的四个O原子和来自一个1,10 - 菲咯啉配体的两个N原子配位。其中一个羧基桥连Cu(II)原子,形成沿b轴延伸的锯齿链。这些链通过芳香环之间的π - π相互作用(质心间距为3.567 (1) Å)以及羧酸盐基团与无序水分子之间的氢键相连,形成三维网络。
