Synthesis and Crystal Structure of Ba4.5Ca1.5La2Fe4O15, Ba5CaEu2Fe4O15 and Ba5CaNd2Co4O15The compounds (I) Ba4.5Ca1.5La2Fe4O15, (II) Ba5CaEu2Fe4O15 and (III) Ba5CaNd2Co4O15 were prepared and investigated by single crystal X-Ray technique. They belong to the Ba6Nd2Al4O15 typ, space group C6v4—P63mc, (I): a = 11.677, c = 6.959 Å; (II): a = 11.570, c = 6.892 Å; (III): a = 11.604, c = 6.839 Å, Z = 2. The crystal chemistry of these substances will be discussed.
Notes:
Die Verbindungen (I) Ba4,5Ca1,5La2Fe4O15, (II) Ba5CaEu2Fe4O15 und (III) Ba5CaNd2Co4O15 wurden einkristallin dargestellt und röntgenographisch untersucht. Sie kristallisieren im Ba6Nd2Al4O15-Typ, Raumgruppe C6v4—P63mc mit (I): a = 11,677, c = 6,959 Å; (II): a = 11,570, c = 6,892 Å; (III): a = 11,604, c = 6,839 Å, Z = 2. Die Kristallchemie dieser Stoffe wird diskutiert.
