摘　　要：A novel phosphonate-based chiral metal-organic framework 1 was synthesized from C2-symmetric 1,1？-biphenol-based ligand and structurally characterized by single-crystal and powder X-ray diffraction, Fourier-transform infrared spectra（FTIR）, circular dichroism（CD） and thermogravimetric analyses（TGA）. Two neighboring Mn ions are linked by two carboxylate groups and one phosphate group to form a di-manganese unit [Mn2] and each [Mn2] cluster in 1 is linked by five ligands, generating a 3D network with fns topology. In addition, the photoluminescence properties of 1 and H4 L were investigated.A novel phosphonate-based chiral metal-organic framework 1 was synthesized from C2-symmetric 1,1？-biphenol-based ligand and structurally characterized by single-crystal and powder X-ray diffraction, Fourier-transform infrared spectra（FTIR）, circular dichroism（CD） and thermogravimetric analyses（TGA）.
