Ba2Bi2[Zn(PO4)4]: Ionic-Isolation-Activated First Barium Bismuth Zincophosphate with Unprecedented ∞[Zn(PO4)4]10- Chains and Balanced Overall Performance Exploration of ultraviolet phosphates with balanced overall performance is of great significance and difficulty. Herein, the first barium bismuth zincophosphate, Ba2Bi2[Zn(PO4)4], was rationally obtained by ion-mixing and anionic condensation, while single crystals of Ba2Bi2[Zn(PO4)4] were obtained by high temperature molten salt method.
