K2NiF4-type structure

Galasso and Darby [220] prepared and investigated the oxyfluoride K2NbC>3F, which has crystal structure similar to K2Ta02F and crystallizes in a K2NiF4 type structure. The structure of the compound consists of infinite layers of octahedrons, Nb04F2, that are oriented perpendicular to the c axis, as shown in Fig. 34. [Pg.92]

Mn04 (M = Pr - Gd) have the K2NiF4-type structure. Included in the second group is EuMA104 (M = La- Gd), in which the Eu2+ and M3+ ions coexist in identical sites. [Pg.481]

The perovskite stracture tolerates relatively large nonstoichiometries and substitutions, while a number of perovskite-related stmctures (with perovskite building blocks) are formed when excesses, deficiencies or substitutions beyond the solubility limits lead to ordered defects and new phases. These comprise, for instance, oxygen deficiency (brownmillerite, ABO2.5), and A excess (K2NiF4-type structure, A2BO4) and ordered intermediate phases. [Pg.20]
