Herein, we systematically synthesize a library of PBAs from binary to high-entropy by a facile coprecipitation method. 
coprecipitation method
The coordination environment in PBAs is explored by X-ray absorption fine structure spectroscopy, which together with elemental mapping confirm the successful introduction of all metals.

elemental mapping
We believe that a wide range of new materials obtained from our coprecipitation and pyrolysis methodology can promote further developments in research on PBA systems and sulfur hosts.
