Abstract
Abstract A new acentric borate, K 2 Na 3 [{B 6 O 10 (OH)}‐{B 3 O 4 (OH) 3 }] ⋅ H 2 O ( 1 ) has been made under solvothermal condition. 1 has layered structure made by B 6 O 13 (OH)‐based chains and B 3 O 5 (OH) 3 ‐bridging clusters. Second‐harmonic generation (SHG) measurements reveal that 1 is a phase‐matchable nonlinear optical (NLO) material, showing the SHG signal intensity of 1.8 times that of KDP (KH 2 PO 4 ). Besides, UV‐Vis diffuse reflectance spectrum shows that 1 has the short deep UV (DUV) absorption cutoff edge of 198 nm. Thermogravimetric analysis reveals it has good thermal stability. Also 1 represents firstly mixed oxoboron clusters‐made 2D layered borate with NLO property.
