Poly[bis-(?4-2,3,5,6-tetra-fluoro-benzene-1,4-di-carboxyl-ato-?(4) O (1):O (1'):O (4):O (4'))bis-(tetra-hydro-furan-?O)dizinc].


ABSTRACT: The title compound, [Zn2(C8F4O4)2(C4H8O)2] n , has a three-dimensional metal-organic framework structure. The asymmetric unit consists of two Zn(II) atoms, two tetrahydrofuran ligands, one 2,3,5,6-tetra-fluoro-benzene-1,4-di-carboxyl-ate ligand and two half 2,3,5,6-tetra-fluoro-benzene-1,4-di-carboxyl-ate ligands, which are completed by inversion symmetry. One Zn(II) atom has a distorted trigonal-bipyramidal coordination geometry, while the other has a distorted octa-hedral geometry. Two independent tetra-hydro-furan ligands are each disordered over two sets of sites with occupancy ratios of 0.48?(4):0.52?(4) and 0.469?(17):0.531?(17).
