Poly[[diaqua-(?(2)-1,4-dioxane-?O:O')(?(2)-2,3,5,6-tetra-fluoro-benzene-1,4-dicarboxyl-ato-?O:O)copper(II)] 1,4-dioxane disolvate dihydrate].

ABSTRACT: In the title complex, {[Cu(C(8)F(4)O(4))(C(4)H(8)O(2))(H(2)O)(2)]·2C(4)H(8)O(2)·2H(2)O}(n), the Cu(II) ion is six-coordinated by two oxygen donors from two trans 2,3,5,6-tetra-fluoro-1,4-dicarboxyl-ate (BDC-F(4)) ligands, two O atoms from two chair 1,4-dioxane ligands and two O atoms from two terminal water mol-ecules, adopting a distorted octa-hedral coordinated geometry. Each BDC-F(4) anion bridges two Cu(II) ions in a bis-monodentate fashion, forming a [Cu(BDC-F(4))](n) chain. These chains are further linked by bridging 1,4-dioxane ligands, generating a two-dimensional net with approximately recta-ngular grids of 11.253 × 7.654?Å. Such adjacent parallel layers are connected by O-H?O hydrogen bonds between guest water mol-ecules and the uncoordinated carboxyl-ate O atoms and coordinated water mol-ecules into the final three-dimensional supra-molecular network.
