合成了一种新的非中心对称硼磷酸盐RbPbBP_2 O_8，并首次用泡生法成功地生长出了尺寸为23 mm × 18 mm × 7 mm的高质量单晶。晶体属四方晶系，空间群I42 d，晶胞参数a = 7.213（3）埃，c = 13.987（10）埃，Z = 4，V = 727.8（6）埃（3）。结构分析表明，RbPbBP 2 O 8具有BO 4和PO 4四面体通过MO 8（M = Rb/Pb）扭曲多面体相互连接的三维骨架结构。RbPbBP_2 O_8的粉末倍频效应与KH_2 PO_4的粉末倍频效应相似。对晶体进行了热分析和透射光谱分析。
A new noncentrosymmetric borophosphate, RbPbBP2O8, has been synthesized and its high quality single crystal with dimensions up to 23 mm x 18 mm x 7 mm was successfully grown by the Kyropoulos method for the first time. It crystallizes in the tetragonal system, space group I42d with cell parameters a = 7.213(3) angstrom, c = 13.987(10) angstrom, Z = 4, V = 727.8(6) angstrom(3). The structure analysis reveals that RbPbBP2O8 features a three-dimensional framework composed of BO4 and PO4 tetrahedra interconnected by MO8 (M = Rb/Pb) distorted polyhedra. The powder second harmonic generation effect of RbPbBP2O8 is similar to that of KH2PO4. Thermal analysis and transmittance spectroscopy were also performed on the reported crystal.
