KZrF(SbF)(SbF) and K(ZrF)(SbZrF): Two Zirconium Fluoroantimonites with Low Dimensional Structures and Wide Transparency Range.

The first examples of zirconium fluoroantimonites, namely, KZrF(SbF)(SbF) and K(ZrF)(SbZrF), have been successfully synthesized by facial hydrothermal reactions. KZrF(SbF)(SbF) features a unique 1D (ZrSbF) double-chain structure, while K(ZrF)(SbZrF) displays a special 0D construction composed of ZrSbF tetranuclear clusters and isolated ZrF octahedra. The two fluorides can exhibit a broad transparency range with almost no absorption peaks from ultraviolet to near-IR. For K(ZrF)(SbZrF), a phase transformation was found before decomposition. The band structures, density of states, and linear-optical properties for the title compounds were also obtained.
