The corner-sharing octahedral tilt angles range from 25-35°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to two equivalent Ba(1), one Ca(1), one Eu(1), and one Bi(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to one Ba(1), two equivalent Ca(1), one Eu(2), and one Bi(2) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Ba(1), one Ca(1), one Eu(1), and one Bi(1) atom.
