Abstract: In the title complex, {[Cu(C8F4O4)(C4H8O2)(H2O)2]·2C4H8O2·2H2O}n, the CuII ion is six-coordinated by two oxygen donors from two trans 2,3,5,6-tetrafluoro-1,4-dicarboxylate (BDC-F4) ligands, two O atoms from two chair 1,4-dioxane ligands and two O atoms from two terminal water molecules, adopting a distorted octahedral coordinated geometry. Each BDC-F4 anion bridges two CuII ions in a bis-monodentate fashion, forming a [Cu(BDC-F4)]n chain. These chains are further linked by bridging 1,4-dioxane ligands, generating a two-dimensional net with approximately rectangular grids of 11.253 × 7.654 Å. Such adjacent parallel layers are connected by O-H...O hydrogen bonds between guest water molecules and the uncoordinated carboxylate O atoms and coordinated water molecules into the final three-dimensional supramolecular network.
