Abstract

The first alkali-earth metal lead(II) oxyhalide Ba₈SrPb₂₄O₂₄Cl₁₈ characterized by fascinating multimember-ring layers has been discovered. Theoretical and experimental investigations illustrate that Ba₈SrPb₂₄O₂₄Cl₁₈ exhibits a moderate band gap of 3.09 eV, incongruent melting behavior and birefringence of 0.014@1064 nm. This discovery may offer new ideas for regulating the optical properties of oxyhalides and broadening their structural diversity.
