| Low Temperature Crystal Growth and Structure of Ordered Ba7F12Cl2  | | | | Abstract
| of composition Ba7F12Cl2 were obtained by a reaction at room temperature be tween Ba2+/Cl"/F_ in a gel of agar-agar/water. The hexagonal crystals have space group P6, «=1064.69(8), c=417.89(5)pm, V=410.24(8) 106 pm3 and Z=l. The anions form a propeller type network located in tunnels parallel to the chex axis; the chloride ions are located at the center on the propeller axes. The Ba2+ ions are coordinated by a (distorted) tricapped trigo nal environment of fluoride and chloride anions. Disorder is present for one particular Ba2+ site. The average structure is isotypic with the structure of Pb7F)2Cl2. | | | |
