Single crystal of the semiorganic NLO material NaB(L-C₄H₄O₅)₂ has been grown with sizes up to 8 ¡Á 5 ¡Á 2 mm³ by the slow evaporation method. The crystal structure of this compound was determined by single crystal X-ray diffraction. It crystallizes in the Monoclinic space group P2 with lattice parameters a = 5.4045(11) ?, b = 11.692(2) ?, c = 9.4773(19) ? and Z = 2. Thermal analysis demonstrated NaB(L-C₄H₄O₅)₂ are thermally stable up to 280 ¡ãC. NaB(L-C₄H₄O₅)₂ exhibits an absorption edge about 220 nm in the UV region. The powder second-harmonic generation (SHG) measurement performed on the ground crystal indicates that it has a NLO efficiency of about 2 times that of KDP (KH₂PO₄) standard. In addition, the origin of stronger SHG effect was discussed.
