Abstract

Ba0.5Sr0.5TiO(C2O4)2·5H2O, which is used as a precursor for Ba0.5Sr0.5TiO3 (BST), has been characterized by X-ray powder diffraction. In accordance with the known structure of BaTiO(C2O4)2·yH2O, the crystal system was found to be monoclinic with unit cell parameters: a=1.3965(1) nm, b=1.3811(2) nm, c=1.3306(2) nm, and β=92.15(1)°. The space group is P21/n, ρ=2.292(2) g cm−3, and Z=8.
