Two novel three-dimensional 3d-4f heterometallic-organic frameworks {[TbZn­(BPDC)2­(μ2-H2O)­Cl­(H2O)3]­·5H2O­·0.5DMA}n (1) and {[TbCo­(BPDC)2­(μ2-H2O)­Cl­(H2O)3]­·8H2O­·0.5DMA}n (2) have been synthesized and structurally characterized. They are isostructural and exhibit irregular one-dimensional channels with a large potential pore volume. Importantly, both of them demonstrate excellent catalytic activity for the chemical fixation of CO2 into cyclic carbonates under mild conditions. Moreover, the catalytic recycling of compound 1 as a representative example was explored; it can be easily separated and reused for at least four times without significant reduction in catalytic ability.
