Summary: Synthetic conditions and ligands play a crucial role in the structure formation of metal-organic frameworks (MOFs). This study presents the synthesis and structural characterization of two novel Co(II)-based MOFs, HL-8 and HL-9. HL-8 exhibits an orthorhombic grid layer structure, while HL-9 is assembled through Co4(OH)2 clusters with organic ligands. Remarkably, HL-9 shows enhanced performance in CO2 adsorption/catalytic transformation and size selectivity during dye molecular adsorption due to its finite cage-like structure.
