• It crystallizes in the noncentrosymmetric Monoclinic space group P2.
• Thermal analysis demonstrated NaB(L-C4H4O5)2 are thermally stable up to 280.
• NaB(L-C4H4O5)2 has an absorption edge about 220 nm in the UV region.
• It exhibits a NLO efficiency of about two times that of KDP (KH2PO4) standard.

Single crystal of the semiorganic NLO material NaB(L-C4H4O5)2 has been grown with sizes up to 8 × 5 × 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) Å, b = 11.692(2) Å, c = 9.4773(19) Å and Z = 2. Thermal analysis demonstrated NaB(L-C4H4O5)2 are thermally stable up to 280 °C. 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.
