Crystal structure of bis-(?-2,3,4,5-tetra-fluoro-benzoato-?(2) O:O')bis-[(1,10-phen-anthroline-?(2) N:N')(2,3,4,5-tetra-fluoro-benzoato-?O)copper(II)] dihydrate.

ABSTRACT: 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 ?-? 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].
