BPO4 is quartz (alpha)-derived structured and crystallizes in the trigonal P3_121 space group. B(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form BO4 tetrahedra that share corners with four equivalent P(1)O4 tetrahedra. P(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form PO4 tetrahedra that share corners with four equivalent B(1)O4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one B(1) and one P(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one B(1) and one P(1) atom.
