Abstract

Single crystals of Li₃Cs₂B₅O₁₀ have been synthesized and its structure determined by single-crystal X-ray diffraction. Li₃Cs₂B₅O₁₀ crystallizes in the non-centrosymmetric space groupC222₁ (No. 20). The structure consists of isolated B₅O₁₀ groups that are bridged by LiO_n (n = 4, 5) and CsO_n (n = 8, 10) polyhedra through their vertex oxygen atoms to form an infinite three-dimensional structure. Li₃Cs₂B₅O₁₀ melts congruently and exhibits a short-wavelength absorption onset at 175 nm. As-prepared Li₃Cs₂B₅O₁₀ is both non-centrosymmetric and phase matchable as supported by second harmonic generation measurements.
