Yang, Kun published the artcileSynthesis, structure, and the second-order nonlinear optical properties of a borate-carboxylic acid compound: KB(L-(-)-C4H4O5]2m·H2O, Application of (S)-2-hydroxysuccinic acid, the main research area is potassium bismalic acid borate second order nonlinear optical property.
A new organic-inorganic hybrid noncentrosym. potassium bis(malic acid)-borates KB(L-(-)-C4H4O5)2·H2O was synthesized by solution method. It was characterized by elemental anal., FT-IR, TGA and single-crystal X-ray crystallog. It crystallizes in the monoclinic space group P21/c with a = 5.546(6), b = 11.985(13), c = 9.952(11) β, β = 97.522(17)°, V = 655.8(13) Δ3, 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 mols., 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
