Ba8SrPb24O24Cl18: the first alkali-earth metal lead(ii) oxyhalide with an intriguing multimember-ring layer

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 birefringe...

Description
Summary: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.
