采用表面热法合成了一种新的发光晶体硼酸镓钠（Na 7 Ga 2B 13 O24（OH）4（1）），并通过X射线单晶结构分析、红外光谱、热重分析、粉末X射线衍射和紫外-可见光谱对其进行了表征。1的晶体数据为：单斜晶系，C2/c，a= 9.9918（8）B= 8.4550（8），c= 26.596（3），β= 94.279（6）o，V= 2240.6（3），Z= 4.化合物1具有三维骨架结构，含有两种不同的氧硼骨架结构单元，即B3 O 6（OH）和B7 O 14（OH）2单元，通过氧桥或四面体Ga 3+中心连接。迄今为止，表面活性剂介质在金属硼酸盐合成中的使用相对未被探索。化合物1发射蓝光。UV-Vis光谱研究表明，1是一种宽带隙半导体。我们的研究结果提供了一个新的机会，生长不同的晶体金属硼酸盐使用表面热策略。
A new crystalline luminescent sodium gallium borate, namely, Na7Ga2B13O24(OH)4(1), has been successfully synthesized through a surfactant-thermal method, and characterized by single-crystal X-ray structural analysis, infrared spectroscopy, thermogravimetric analysis, powder X-ray diffraction, and UV–Vis spectroscopy. Crystal data for1: monoclinic,C2/c,a= 9.9918(8) Å,b= 8.4550(8) Å,c= 26.596(3) Å,β= 94.279(6)o,V= 2240.6(3),Z= 4. Compound1displays a 3D framework and contains two different oxoboron framework building blocks, namely B3O6(OH) and B7O14(OH)2units, linked by oxo bridges or by tetrahedral Ga3+centres. To date, the use of surfactant media in the synthesis of metal borates is relatively unexplored. Compounds1emits blue luminescence. UV–Vis spectral investigation indicates that1is a wide-band-gap semiconductor. Our results offer a new opportunity to grow diverse crystalline metal borates using surfactant-thermal strategy.
