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.
