摘要：

A chiral lanthanide metal-organic framework based on enantiopure camphoric acid (D-H(2)cam), [Nd-3(D-cam)(8)(H2O)(4)Cl](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 P2(1)2(1)2(1) with a = 13.8287(7), b = 14.0715(7), c = 25.7403(12) angstrom, V = 5008.8(4) angstrom(3), M-r = 1333.08, Z = 4, F(000) = 2644, D-c = 1.768 g/cm(3), mu(MoKa) = 3.189 mm-1, the final R = 0.0351 and wR = 0.0814 (I > 2 sigma(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.
