Semiorganic nonlinear optical material: preparation and properties of (NH(4)).Sr[l-(+)-C(4)H(2)O(6).B(OH)(2)].4H(2)O.
The synthesis, crystal structure, and characterization of the noncentrosymmetric semiorganic material (NH(4)).Sr[l-(+)-C(4)H(2)O(6).B(OH)(2)].4H(2)O were reported. Crystals were synthesized through slow evaporation at room temperature, utilizing SrCl(2).6H(2)O, C(4)H(4)O(6), H(3)BO(3), and NH(3).H(2)O as reagents, and its structure was determined by single-crystal X-ray diffraction. It crystallizes in the triclinic space group P1 (No. 1) with a = 6.4633(10) A, b = 7.0452(13) A, c = 7.0745(12) A, alpha = 85.351(5) degrees , beta = 77.678(5) degrees , gamma = 73.276(4) degrees , and Z = 1. It exhibits a two-dimensional layered structure along the c axis, consisting of SrO(9) polyhedra, BO(4) tetrahedra, tartrate molecules, NH(4)(+) cations, and H(2)O molecules. IR spectroscopy, UV-vis diffuse-reflectance spectroscopy, thermal analysis, and second-harmonic generation (SHG) were also performed on the reported material. Nonlinear optical measurements, using 1064 nm radiation, indicate that the material has SHG properties, with an efficiency of approximately 1.5 times that of KH(2)PO(4).
