Structural study of LiKB4O7 and LiRbB4O7: New nonlinear optical crystals

Ono Y, Nakaya M, Sugawara T, Watanabe N, Siraishi H, Komatsu R, Kajitani T

The title compounds, LiKB4O7 (LKB4) and LiRbB4O7 (LRB4), are newly developed nonlinear optical crystals containing two kinds of anionic groups, (B3O8)(7-) and (B5O10)(5-). The (B3O8)(7-) groups form infinite spiral chains parallel to the [1 0 0] direction, which are interconnected by sharing oxygen atoms with (B5O10)(5-) groups.
