Synthesis and characterization of a new aluminophosphate with a Al3P6O249− three-dimensional framework†
Abstract
A novel mixed-alkali metal aluminophosphate, K6Na3Al3P6O24, has been successfully synthesized and structurally characterized. The compound contains a unique Al3P6O249− three-dimensional framework composed of AlO4 and PO4 tetrahedra with an Al/P ratio of 1/2. This compound melts congruently and is optically transparent from 352 to 2600 nm.
