A new C2-symmetric TADDOL-based ligand H4L was designed and synthesized from readily available tartaric acid and was used to construct a novel TADDOL-based chiral metal-organic framework {[Co2L(DMA)(H2O)5]·2DMA}n 1 (DMA =N,N'-dimethylacetamide).It was characterized by single-crystal and powder X-ray diffraction,Fourier-transform infrared spectra (FTIR),solid-state circular dichroism (CD) and thermal gravimetric analysis (TGA).1 crystallizes in the chiral orthorhombic space group P212121 with a =9.7060(8),b =15.5661(1),c =44.564(3) (A),V=6732.9(9) (A)3,Z =4,Mr =1394.08,Dc =1.375 g/cm3,F(000) =2888,GOOF =1.032,the final R=0.0607 and wR =0.1582 for 21374 observed reflections with I＞ 2σ(I).Each Co2 cluster in 1 is linked by three ligands and each ligand is coordinated to three Co2 clusters with one free carboxylate group,thus generating a 2D network.These 2D networks are further extended into a 3D supramolecule framework by the hydrogen bonding interactions (O-H..O) in an A-B-A-B stacking mode.Additionally,the photoluminescence of 1 and H4L were also investigated.
