Sb(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form SbO6 octahedra that share corners with six equivalent Ca(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 34-39°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to one Ca(2), two equivalent Ca(1), one La(1), and one Sb(1) atom.
