Abstract
In the presence of different cations, reactions of [SbBr6]3− and I2 result in a new family of diverse supramolecular 1D polyiodide‐bromoantimonate networks. The coordination number of Sb, as well as geometry of assembling {Ix}n− polyhalide units, can vary, resulting in unprecedented structural types. The nature of I⋅⋅⋅Br interactions was studied by DFT calculations; estimated energy values are 1.6–6.9 kcal mol−1. Some of the compounds showed strong photoconductivity in thin films, suggesting multiple feasible applications in optoelectronics and solar energy conversion.
