A novel indium-based chiral metal organic-framework 1 {In2L(μ2-O)(H2O)3}n was synthesized from C2-symmetric 1,1΄-biphenol-based ligand H4L and structurally 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 monoclinic space group P21 with a = 10.1861(5), b = 18.5632(9), c = 16.5153(8) Å, V = 3077.1(3) Å3, Z = 2, Mr = 944.29 g/mol, Dc = 1.019 g/cm3, F(000) = 944, GOOF = 0.932, the final R = 0.0577 and wR = 0.1091 for 22090 observed reflections with I > 2σ(I). Each In2 cluster in 1 is linked by four ligands and each ligand is coordinated to four In2 clusters to generate a 3D network. Additionally, the photoluminescence of 1 and H4L were also investigated.
