In the title compound, [Cu2(C7HF4O2)4(C12H8N2)2]·2H2O, the Cu(II) ion has a square-pyramidal coordination sphere. The basal plane consists of two N atoms [Cu-N = 2.008 (3) and 2.032 (3) Å] from the phenanthroline ligand, and of two carboxyl-ate O atoms [Cu-O = 1.942 (3) and 1.948 (3) Å] from two 2,3,4,5-tetra-fluoro-benzoate anions. Another 2,3,4,5-tetra-fluoro-benzoate anion provides the apical carboxyl-ate O atom [Cu-O = 2.262 (3) Å] and bridges two Cu(II) ions into a binuclear centrosymmetric dimer. Intra-molecular π-π inter-actions between one of the tetra-fluoro-benzene rings and the middle of the phenenanthroline rings [3.617 (3) Å] stabilize the mol-ecular configuration. O-H⋯O hydrogen bonds between the lattice water mol-ecules and the unbound carboxyl-ate O atoms of the metal complexes leads to the formation of a chain structure parallel to [100].
在标题化合物[Cu2(C7HF4O2)4(C12H8N2)2]·2H2O中，Cu(II)离子具有一个四方锥配位环境。基面由来自菲咯啉配体的两个N原子[Cu-N = 2.008 (3) 和2.032 (3) Å]以及来自两个2,3,4,5-四氟苯甲酸根阴离子的两个羧酸根O原子[Cu-O = 1.942 (3) 和1.948 (3) Å]组成。另一个2,3,4,5-四氟苯甲酸根阴离子提供顶端羧酸根O原子[Cu-O = 2.262 (3) Å]，并将两个Cu(II)离子桥联成一个双核中心对称二聚体。一个四氟苯环与菲咯啉环中间之间的分子内π-π相互作用[3.617 (3) Å]稳定了分子构型。晶格水分子与金属配合物未配位的羧酸根O原子之间的O-H⋯O氢键导致形成平行于[100]的链状结构。
