A novel three-dimensional metal-organic framework, [Cu2I2](0.5)[Cu-2(CO2)(4)(C10H7N2)(4)](0.5)center dot 2DMF (JLU-Liu14), has been synthesized under solvothermal conditions, which is constructed by ternary secondary building units (SBUs): classical Cu-2(CO2)(4) paddle-wheel unit, Cu2I2 dimer unit, and organic SBU. In JLU-Liu14, the pyrimidine groups of 4-PmBC (4-(pyrimidin-5-yl) benzoic acid) ligands coordinated to copper paddle-wheel and Cu2I2 dimer units to form a zigzag chain, and the zigzag chains then connected together by 4-PmBC ligands to generate a three-dimensional framework with (3,4,6)-connected topology. There are two types of channels along the c axis with the dimensions of 14 x 14 angstrom and 5 x 5 angstrom, respectively, in which the big hexagonal channel is surrounded by six small trigonal channels. In addition, JLU-Liu14 displays the interesting ability of the uptake and release of iodine.
