Synthesis, Structure, and the Second-order Nonlinear Optical Properties of a Borate-carboxylic Acid Compound: KB[L-（-）-C4H4O5]2·H2O

论文摘要

A new organic-inorganic hybrid noncentrosymmetric potassium bis（malic acid）-borates KB（L-（-）-C4H4O5）2·H2O was synthesized by solution method. It was characterized by elemental analysis, FT-IR, TGA and single-crystal X-ray crystallography. It crystallizes in the monoclinic space group P21/c with a = 5.546（6）, b = 11.985（13）, c = 9.952（11） ?, β = 97.522（17）°, V = 655.8（13） ?3, Z = 2, Dc = 1.682 g/cm3, μ（MoKa） = 0.46 mm–1 and F（000） = 340. 5009 reflections were measured and 2893 independent reflections(Rint = 0.051) were used for further refinement. Single-crystal X-ray diffraction reveals that the complex exhibits a threedimensional pseudo tunnel structure consisting of fundamental building block [B（L-（-）-C4H4O5）2]– anions. The small cavities are occupied by the H2O molecules, which stabilize the whole structure by O–H×××O hydrogen bonds. The complex exhibits nonlinear optical effect as high as 1.5 times that of KDP standard.
