英文摘要	Incommensurately modulated borate structures of a new type were studied in detail in the nonlinear optical (NLO) materials Cs2TB4O9 (T = Ge, Si) using single-crystal X-ray diffraction techniques. The structures were solved by the charge-flipping algorithm in the superspace group I2(alpha beta 0)0. The refinement results strongly suggest that the main structure modulation feature of Cs2TB4O9 is the ordering of the O atoms. With these modulated structure models, the unreasonable B-O distances in the average structures were explained as the ordering of BO4 and BO3.; National Natural Science Foundation of China [91222107, 21321001, 21471009]; SCI(E); EI; PubMed; ARTICLE; mjg@fjirsm.ac.cn; junliang.sun@pku.edu.cn; Pt 2; 194-200; 72
