An 8-Connected Chiral Lanthanide Metal-organic Framework Constructed from Naturally Camphoric Acid:Crystal Structure, Vibrational Circular Dichroism Spectroscopy and Second-order Nonlinear Optical Effect
摘要:
A chiral lanthanide metal-organic framework based on enantiopure camphoric acid (D-H2cam),[Nd3(D-cam)8(H2O)4Cl]n (1), has been synthesized and characterized by single-crystal X-ray structural analysis, elemental analysis, IR, thermal gravimetric, and X-ray powder diffraction. Crystal data for the title compound are as follows:orthorhombic system, space group P212121 with a=13.8287(7), b=14.0715(7), c=25.7403(12) Å, V=5008.8(4) Å3, Mr=1333.08, Z=4, F(000)=2644, Dc=1.768 g/cm3, μ(MoKα)=3.189 mm-1, the final R=0.0351 and wR=0.0814 (I>2σ(I)). Compound 1 displays an 8-connected bcu topology 3D framework and hydrogen-bonding interactions stabilize the solid-state structure. The vibrational circular dichroism (VCD) spectrum and second-order nonlinear optical effect of compound 1 have been studied in the solid state.
