Ca5PO43PO3F3
Ca5PO43PO3F3 is a chemical compound with the formula calcium phosphate fluoride. It is a mixed phosphate-fluoride salt of calcium. The structure contains calcium cations (Ca2+) and a combination of phosphate (PO43-) and fluorophosphate (PO3F3-) anions. This compound is known to exist and has been synthesized and characterized. Its properties are of interest in materials science and potentially in applications where specific calcium phosphate or fluoride-containing materials are desired. The synthesis typically involves reactions between calcium salts and sources of phosphate and fluoride ions under controlled conditions. Crystallographic studies have been performed to determine its precise atomic arrangement. The presence of both phosphate and fluorophosphate groups suggests a potential for varied chemical behavior and physical properties compared to simple calcium phosphates or calcium fluorides. Further research may explore its stability, solubility, and potential uses in areas such as bioceramics or as a precursor material.
