Description

Potassium yttrium erbium tetrafluoride is a fluorite-related superstructure and is isomorphic with KYF4. The Ln2F12 groups which form chains in the three cationic layers perpendicular to the c axis consist of two edge-shared fluorine pentagonal LnF7 bipyramids. One of the pyramids is centred by a Y atom, the other by (0.9Y+0.1Er), this accounts for the Y/Er ratio of 0.95/0.05 in the unit cell. (orig.)
