Abstract
We report a novel complex polyhalide family (A<sub>2</sub>TeBr<sub>6</sub>I<sub>2</sub>), containing [TeBr<sub>6</sub>]<sup>2−</sup> octahedra interconnected by I<sub>2</sub> bridge-molecules <italic>via</italic> halogen bonding. They are narrow bandgap semiconductors, show strong photoresponse and are easily synthesized from aqueous solution.
