Two structurally similar metal-organic frameworks (MOFs) [DyCuI(IN)(DMF)]·DMF () and [DyCuI(IN)(DMA)]·DMA () (HIN = isonicotinic acid) feathering different coordinated solvent molecules were successfully isolated by tuning the types of solvents in the reaction system. Structural tests indicate that and are both built from 1D Dy(III) chains and copper iodide clusters [CuI], generating into three-dimensional frameworks with an open 1D channel along the axis. and display extensive and excellent solvent stability.
