The structure described by Ba(PO4)2 crystallizes in the triclinic P-1 space group. Ba(1) is bonded in a 9-coordinate geometry to one O(1), one O(4), one O(5), one O(6), one O(8), two equivalent O(2), and two equivalent O(3) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded in a tetrahedral geometry to one O(4), one O(6), one O(7), and one O(8) atom. In the second P site, P(2) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(5) atom. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one Ba(1) and one P(2) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Ba(1) and one P(2) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Ba(1) and one P(2) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one Ba(1) and one P(1) atom. In the fifth O site, O(5) is bonded in a single-bond geometry to one Ba(1) and one P(2) atom. In the sixth O site, O(6) is bonded in a distorted single-bond geometry to one Ba(1) and one P(1) atom. In the seventh O site, O(7) is bonded in a single-bond geometry to one P(1) atom. In the eighth O site, O(8) is bonded in a distorted single-bond geometry to one Ba(1) and one P(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
