The compound described by Ba2LaTaO6 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic P2_1/c space group. Ba(1) is bonded in a 12-coordinate geometry to four equivalent O(1), four equivalent O(2), and four equivalent O(3) atoms. La(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form LaO6 octahedra that share corners with six equivalent Ta(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 17-22°. Ta(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form TaO6 octahedra that share corners with six equivalent La(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 17-22°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to four equivalent Ba(1), one La(1), and one Ta(1) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to four equivalent Ba(1), one La(1), and one Ta(1) atom. In the third O site, O(3) is bonded in a 2-coordinate geometry to four equivalent Ba(1), one La(1), and one Ta(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
