The structure described by CaBPO5 crystallizes in the trigonal P3_121 space group. Ca(1) is bonded in a 10-coordinate geometry to two equivalent O(1), four equivalent O(2), and four equivalent O(3) atoms. B(1) is bonded to two equivalent O(1) and two equivalent O(3) atoms to form BO4 tetrahedra that share corners with two equivalent B(1)O4 tetrahedra and corners with two equivalent P(1)O4 tetrahedra. P(1) is bonded to two equivalent O(2) and two equivalent O(3) atoms to form PO4 tetrahedra that share corners with two equivalent B(1)O4 tetrahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to two equivalent Ca(1) and two equivalent B(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Ca(1) and one P(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to two equivalent Ca(1), one B(1), and one P(1) atom. is represented by the CIF card [CIF]
