Abstract

Currently, short-wavelength nonlinear optical materials are urgently needed. Through substituting homoleptic [LiO₄] in centrosymmetric LiRbSO₄ with heteroleptic [LiO₃Cl] tetrahedra, an acentric sulfate chloride, Li₂RbSO₄Cl, was designed and synthesized by the high-temperature melting method. Li₂RbSO₄Cl shows a relatively short ultraviolet absorption edge (<200 nm) among newly reported sulfate chlorides. Millimeter-sized crystals were grown due to the congruent melting behavior and high thermal stability of the compound.
