摘要：A series of isomorphic metal-organic frameworks, namely, [Cd-3(IN)(4)(N-3)(2)(DMA)(2)]center dot 2DMA (1), [Cd-3(IN)(4)(N-3)(2)(NMP)(2)]center dot 2NMP (2), [Cd-3(IN)(4)(N-3)(2)(DMI)(2)]center dot 2DMI (3), [Cd-3(TP)(4)(N-3)(2)(DMA)(2)]center dot 4DMA center dot H2O (4), [Cd-3(TP)(4)(N-3)(2)(NMP)(2)]center dot 4NMP center dot H2O (5), and [Cd-3(TP)(4)(N-3)(2)(DMI)(2)]center dot 4DMI (6), where HIN = isonicotinic acid and HTP = 4-tetrazole pyridine, have been synthesized via solvothermal reaction with Cd(NO3)2 center dot 4H(2)O in three different solvents [N, N-dimethylacetamide (DMA), N-methylpyrrolidinone (NMP), and 1,3-dimethyl-2-imidazolidinone (DMI)]. Single-crystal X-ray structure analysis reveals that compounds 1-6 show threedimensional (3D) 6-connected nets with channels based on trinuclear cadmium clusters. The coordinated and lattice solvent molecules occupy the free void spaces of the channels. Induced by different solvent molecules, the solvent-accessible volumes of these MOFs are 3 > 2 > 1 and 6 > 5 > 4, which is consistent with the sizes of solvents (DMI > NMP > DMA). By comparing 1-3 with 4-6, the longer organic anion is beneficial to construct MOFs with larger porous sizes and higher solvent-accessible volumes.
