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).
标题化合物[Zn₂(C₈F₄O₄)₂(C₄H₈O)₂]ₙ具有三维金属有机骨架结构。不对称单元由两个Zn(II)原子、两个四氢呋喃配体、一个2,3,5,6 - 四氟苯 - 1,4 - 二羧酸酯配体和两个半的2,3,5,6 - 四氟苯 - 1,4 - 二羧酸酯配体组成，后者通过反演对称性完成。一个Zn(II)原子具有扭曲的三角双锥配位几何构型，而另一个具有扭曲的八面体几何构型。两个独立的四氢呋喃配体各自在两组位置上无序分布，占有率分别为0.48(4):0.52(4)和0.469(17):0.531(17)。
