BP5(Pb3O10)2 crystallizes in the tetragonal P-4 space group. B(1) is bonded to four equivalent O(2) atoms to form BO4 tetrahedra that share corners with four equivalent P(2)O4 tetrahedra. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 5-coordinate geometry to one O(3), one O(4), one O(5), and two equivalent O(1) atoms. In the second Pb site, Pb(2) is bonded in a 4-coordinate geometry to two equivalent O(3) and two equivalent O(5) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded in a tetrahedral geometry to four equivalent O(3) atoms. In the second P site, P(2) is bonded to one O(1), one O(2), one O(4), and one O(5) atom to form PO4 tetrahedra that share  a cornercorner with one B(1)O4 tetrahedra. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Pb(1) and one P(2) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one B(1) and one P(2) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one Pb(1), one Pb(2), and one P(1) atom.
