On Ordered Perovskites with Cationic Vacancies. IV. Compounds of Type Ba6B2III□Te3VIO18Compounds of the composition Ba6B2III□Te3VIO18 ≙ Ba2B2/3III□1/3TeVIO6, with BIII = Pr, Nd, Sm—Lu, Y crystallize with a cubic perovskite lattice. The cell parameters diminish as the size of BIII falls (BIII = Pr: a = 8.528 Å Lu: a = 8.334 Å). In contrast to the corresponding Perovskites with UVI and WVI no polymorphism is observed.
Notes:
Verbindungen der Zusammensetzung Ba6B2III□Te3VIO18 ≙ Ba2B2/3III□1/3TeVIO6 kristallisieren für BIII = Pr, Nd, Sm—Lu, Y im kubischen Perowskitgitter. Die Gitterkonstanten nehmen mit sinkender BIII-Größe ab (BIII = Pr: a = 8,528 Å Lu: a = 8,334 Å). Im Gegensatz zu den entsprechenden Perowskiten mit UVI und WVI wird keine Polymorphie beobachtet.
