AI Article Synopsis

  • The compound [Zn2(C8F4O4)2(C4H8O)2] n features a three-dimensional metal-organic framework architecture.
  • It consists of two zinc (Zn(II)) atoms, two tetrahydrofuran (THF) ligands, and specific types of tetra-fluoro-benzene-based ligands.
  • The zinc atoms have distinct coordination geometries: one with a distorted trigonal-bipyramidal shape and the other with a distorted octahedral shape, while the THF ligands show some disorder in their arrangement.

Article 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).
