Abstract

Two unprecedented metal borate-iodates, Sr[B(OH)₄](IO₃) (SBIO) and Li₄Sr₅[B₁₂O₂₂(OH)₄](IO₃)₂ (LSBIO), were synthesized via the strategy of introducing (IO₃)⁻ into borates. In particular, the LSBIO possessed a new B₁₂O₂₆ fundamental building block (FBB). The two compounds integrated the advantages of both pure iodates and borates, showing enlarged band gaps and birefringence. Moreover, diverse B–O FBBs achieved the modulation of birefringence. This work reported the first two examples of borate-iodates.
