在溶剂热条件下制备了一种新的非中心对称混合碱性硼酸盐Li2CsB7O10(OH)(4)(1)。这种层状氧化硼框架由独特的鸟状[B7O12(OH)(4)]（7-）团簇组成，具有14环的大孔。其二次谐波产生（SHG）信号为2.5KDP (KH2PO4)，其短紫外截止边表明该晶体是一种潜在的深紫外透明非线性光学材料。
A new noncentrosymmetric mixed-alkaline borate, Li2CsB7O10(OH)(4) (1), was made under solvothermal conditions. This layered boron oxide framework consists of unique bird-shaped [B7O12(OH)(4)](7-) clusters with large 14-ring pores. Its second-harmonic-generation (SHG) signal is 2.5KDP (KH2PO4), with its short ultraviolet (UV) cutoff edge indicating that this crystal is a potential deep-UV transparent nonlinear-optical material.
