Abstract

By dehydration of the known coordination polymers (1)(infinity)[M-II(tF-BDC)(H2O)(4)] (M-II = Co2+, Zn2+ and tF-BDC2- = tetrafluoroterephthalate) the homoleptic anhydrous coordination networks (3)(infinity)[M-II(tF-BDC)] were obtained as polycrystalline powders. Their crystal structures (C2/c, Z = 4) were solved and refined by means of synchrotron powder diffraction data. These structures are characterized by [(MO4)-O-II] tetrahedra, which are connected by the tF-BDC2- linkers to form a 3D non-porous coordination network. The dehydration leads to a change from a [(MO6)-O-II] octahedral coordination in the hydrate to a tetrahedral coordination sphere in the anhydrous compound. For the cobalt compounds this leads to a color change from pale rose to deep blue upon heating and dehydration, which was analyzed by means of UV/Vis/NIR spectroscopy and measurements of the magnetic susceptibilities. In contrast, (1)(infinity)[Ni-II(tF-BDC)(H2O)(4)] can only partly be dehydrated to form (2)(infinity)[Ni-II(tF-BDC)(H2O)(2)] (P1, Z = 1) with retention of the octahedral [(NiO6)-O-II] coordination in both compounds. At higher temperatures the tF-BDC2- linker starts to decompose, before a complete dehydration can take place.
