Mixed crystalline precursor complexes of the type [Ba(C2H6O2)4][Ti1−xSnx(C2H4O2)3] (x=0-1) for BaTi1−xSnxO3 ceramics: Synthesis, structure and calcination

The synthesis of [Ba(C2H6O2)4][Ti(C2H4O2)3], its crystal structure and thermal decomposition is described. This 1,2-ethanediolato complex forms with the isotypic tin compound [Ba(C2H6O2)4][Sn(C2H4O2)3] solid solutions [Ba(C2H6O2)4][Ti1−xSnx(C2H4O2)3] in any ratio. Corresponding mixed crystalline samples are suitable precursor complexes for BaTi1−xSnxO3 ceramics with the feature of a heavy element distribution in molecular scale matching the element distribution of the final ceramics.
