Introduction of the Cl^{鈥?/sup> anion in the borate systems generates a new perovskite-like phase, K₃B₆O₁₀Cl, which exhibits a large second harmonic response, about four times that of KH₂PO₄ (KDP), and is transparent from the deep UV (180 nm) to middle-IR region. K₃B₆O₁₀Cl crystallizes in the noncentrosymmetric and rhombohedral space group R3m. The structure consists of the A-site hexaborate [B₆O₁₀] groups and the BX₃ Cl-centered octahedral [ClK₆] groups linked together through vertices to form the perovskite framework represented by ABX₃.}
