摘要
随着光学科学技术的不断发展，对光学器件的通用性和多应用场景提出了更高的要求。有机-无机杂化双折射晶体因其在分子设计和组装上的高灵活性而受到广泛关注。本文采用水热法制备了在C2/c空间基上结晶的碱土金属2-羟基丁二酸盐Ba3(C4H4O5)2(OH)2。其单位胞参数为a = 20.0584(7) Å， b = 7.4499(3) Å， c = 9.5087(3) Å， β = 96.808(2)°。采用傅里叶变换红外（FTIR）吸收光谱、紫外-可见-近红外漫反射光谱和同步热分析对Ba3(C4H4O5)2(OH)2多晶粉末进行了详细的表征。此外，利用第一性原理计算和Hirshfeld曲面分析进行了理论分析。计算出Ba3(C4H4O5)2(OH)2的理论双折射率为0.1 @546 nm。同时，对Ba3(C4H4O5)2(OH)2的UV - vis - nir漫反射和能带结构计算表明，Ba3(C4H4O5)2(OH)2的间接带隙为5.11 eV，紫外截止边为203 nm。利用有机材料和无机材料的互补特性，Ba3(C4H4O5)2(OH)2是一种很有前途的紫外双折射材料。
Ba3(C4H4O5)2(OH)2: A Novel Short-Wavelength Alkaline Earth Metal 2-Hydroxybutanedioate
With the continuous development of optical science and technology, there are higher requirements for the versatility and multi-application scenarios of optical devices. Organic–inorganic hybrid birefringent crystals have attracted much attention due to their high flexibility in molecular design and assembly. In this work, an alkaline earth metal 2-hydroxybutanedioate Ba3(C4H4O5)2(OH)2 crystallizing in the C2/c space group is synthesized by the hydrothermal method. Its unit cell parameters are a = 20.0584(7) Å, b = 7.4499(3) Å, c = 9.5087(3) Å, and β = 96.808(2) °. Ba3(C4H4O5)2(OH)2 polycrystalline powder is characterized in detail by Fourier transform infrared (FTIR) absorption spectroscopy, UV–vis–NIR diffuse reflectance spectroscopy, and simultaneous thermal analysis. In addition, theoretical analyses are carried out using first-principles calculations and Hirshfeld surface analysis. The theoretical birefringence of Ba3(C4H4O5)2(OH)2 is calculated to be 0.1 @546 nm. At the same time, UV–vis–NIR diffuse reflectance and band structure calculations show that Ba3(C4H4O5)2(OH)2 has an indirect bandgap of 5.11 eV with a UV cutoff edge of 203 nm. By leveraging the complementary attributes of organic and inorganic materials, Ba3(C4H4O5)2(OH)2 stands out as a promising UV birefringent candidate.
