Introduction of the Cl - anion in the borate systems generates a new perovskite-like phase, K 3 B 6 O 10 Cl, which exhibits a large second harmonic response, about four times that of KH 2 PO 4 (KDP), and is transparent from the deep UV (180 nm) to middle-IR region. K 3 B 6 O 10 Cl crystallizes in the noncentrosymmetric and rhombohedral space group R3m. The structure consists of the A-site hexaborate [B 6 O 10 ] groups and the BX 3 Cl-centered octahedral [ClK 6 ] groups linked together through vertices to form the perovskite framework represented by ABX 3 .
