porous coordination polymers, {[Co0.5(TBC)]·2DMF}n (1) and {[Co(TBC)Cl0.5(CH3OH)]·0.5Cl}n (2), were synthesized via the solvothermal reaction of cobalt(II)
salts and 3,5-bis(1H-1,2,4-triazol-1-yl)benzenecarboxylic
acid. Single-crystal X-ray diffraction analyses exhibited that complex 1 contains rtl three-dimensional (3D) skeleton and one-dimensional
channels with large apertures, while complex 2 displays
a novel 2-nodal 3,6-linked 3D structure with a Schläfli sign
of {4.82}2{46.89} and
contains micropores. Meanwhile, compound 2 shows selective
adsorption properties of anionic methyl orange in a water solution.
The dye adsorption studies of 1 and 2 revealed
that the porous character and charge properties of metal–organic
frameworks are two important factors heavily influencing dye adsorption.
