Novel Fluoridoaluminates from Ammonothermal Synthesis: Two Modifications of K<sub>2</sub>AlF<sub>5</sub> and the Elpasolite Rb<sub>2</sub>KAlF<sub>6</sub>

Two new modifications of the pentafluoridoaluminate K<sub>2</sub>AlF<sub>5</sub> were obtained from ammonothermal synthesis at 753 K, 224 MPa and 773 K, 220 MPa, respectively. Both crystallize in the orthorhombic space group type <i>Pbcn</i>, with close metric rel...
