Three porous heterovalent cluster organic frameworks Cu2(H2O)(Cu4I4)(INA)4·solvent (1), Cu2(H2O)2(Cu4I4)2(INA)4(DABCO)2·2DMA (2) and [(Cu2)2(PVBA)8(Cu4I4)]·DMF (3) (HINA = isonicotinic acid, DABCO = 1,4-diazabicyclo[2.2.2]octane, HPVBA = 4-(2-(4-pyridyl)ethenyl) benzoic acid, DMF = N,N′-dimethylformamide, DMA = N,N′-dimethylacetamide) have been solvothermally synthesized and structurally characterized. Crystal structure analyses indicate that compounds 1 and 2 are constructed from planar four-connected Cu2(CO2)4 secondary building units (SBUs) and tetrahedral four-connected Cu4I4 SBUs, while compound 3 is composed of octahedral six-connected Cu2(CO2)4 SBUs and tetrahedral four-connected Cu4I4 SBUs. All these frameworks possess nano-sized 1-dimensional channels. Furthermore, the thermal and chemical stabilities, gas adsorption properties and iodine adsorption/release ability of compound 2 have been systematically studied.
