Poly[bis(ethanol)(μ4-2,3,5,6-tetrafluorobenzene-1, 4-dicarboxylato)cadmium]

Abstract

In the title compound, [Cd(C8F4O4)(C 2H5OH)2]n, the CdII cation sits on an inversion centre and is coordinated by six O atoms from four tetrafluorobenzene-1,4-dicarboxylate anions and two ethanol molecules in a distorted octahedral geometry. The anionic ligand is also located on an inversion centre, and connects four CdII cations, generating a two-dimensional polymeric layer parallel to the ab plane. Within the layer, the ethanol molecule links F and O atoms of the nearest anionic ligands via O - H⋯O and O - H⋯F hydrogen bonds. The ethyl group of the ethanol molecule is disordered over two positions with an occupancy ratio of 0.567(10):0.433(10).
