چکیده
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].

In the title compound, [Cu(2)(C(7)H(4)ClO(2))(4)(C(12)H(8)N(2))(2)]·2H(2)O, the two crystallographically independent dinuclear complex mol-ecules, A and B, have different Cu⋯Cu separations, viz. 3.286 (1) Å in A and 3.451 (1) Å in B. Both independent mol-ecules reside on inversion centres, so the asymmetric unit contains a half-mol-ecule each of A and B and two water mol-ecules. Each Cu atom ha...
