英文摘要 | Mixed-anion compounds are among the most promising systems to design functional materials with enhanced properties. Among the phosphate-sulfate species, the [SO4](2-) and [PO2F2](-) tetrahedra are known and give rise to structural versatility. However, to date, the crystal structures of phosphate-sulfates with the coexistence of two distinct anion groups ([S2O7](2-) and [PO2F2](-)) in one compound are unknown. Here, a novel type of fluorooxophosphorsulfate, K-4(PO2F2)(2)(S2O7) (KSPOF), is designed and synthesized via a high-temperature method in a closed system. The crystal structure is derived from single-crystal X-ray diffraction (C2/c, a = 13.000(10) angstrom, b = 7.5430(10) angstrom, c = 19.010(10) angstrom, beta = 130.070(10)degrees, and Z = 4). It is the first fluorooxophosphorsulfate with mixed-anion building units ([S2O7](2-) and [PO2F2](-)) and a unique drum-like cluster was found, which enriches the diversity of structures for fluorooxophosphorsulfate systems. Furthermore, the theoretical calculations indicate that KSPOF possesses moderate birefringence, which mainly originates from the distorted [PO2F2](-) tetrahedron. |
