Ba(1) is bonded in a 11-coordinate geometry to one O(1), one O(6), one O(7), two equivalent O(2), two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a rectangular see-saw-like geometry to two equivalent O(5) and two equivalent O(7) atoms. In the second Cu site, Cu(2) is bonded in a square co-planar geometry to two equivalent O(2) and two equivalent O(4) atoms. P(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(5) atom. Te(1) is bonded in a distorted rectangular see-saw-like geometry to one O(1), one O(4), one O(6), and one O(7) atom. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Ba(1), one P(1), and one Te(1) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to two equivalent Ba(1), one Cu(2), and one P(1) atom. In the third O site, O(3) is bonded in a single-bond geometry to two equivalent Ba(1) and one P(1) atom. In the fourth O site, O(4) is bonded in a 2-coordinate geometry to two equivalent Ba(1), one Cu(2), and one Te(1) atom. In the fifth O site, O(5) is bonded in a distorted bent 120 degrees geometry to two equivalent Ba(1), one Cu(1), and one P(1) atom. In the sixth O site, O(6) is bonded in a distorted bent 120 degrees geometry to two equivalent Ba(1) and two equivalent Te(1) atoms. In the seventh O site, O(7) is bonded in a 3-coordinate geometry to one Ba(1), one Cu(1), and one Te(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
