Two novel complexes [M(ImH)(6)](tfbdc) (M=Co, Ni; ImH=imidazole, tfbdc=2,3,5,6-tetrafluoroterephthalate) were synthesized and characterized by elemental analysis, IR spectra, thermogravimetric analysis, cyclic voltammetry, and X-ray single crystal structure analysis. Both [Co(ImH)(6)](tfbdc) (1) and [Ni(ImH)(6)] (tfbdc) (2) all crystallize in the monoclinic system, space group P2(1)/c, and with Z=2. Metal ions have all octahedral geometry coordinated by six N atoms from six imidazole molecules. The independent components, [M(ImH)(6)](2+) cations and tfbdc anions are connected into a three-dimensional supramolecular network by N-H center dot center dot center dot O and C-H center dot center dot center dot F hydrogen bonds.
