The crystal structure described by K3B5PH2O13 crystallizes in the monoclinic P2/c space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to one O(1), one O(3), one O(4), one O(5), one O(6), one O(7), and two equivalent O(2) atoms. In the second K site, K(2) is bonded in a 12-coordinate geometry to two equivalent H(1), two equivalent O(3), two equivalent O(4), two equivalent O(5), two equivalent O(6), and two equivalent O(7) atoms. There are three inequivalent B sites. In the first B site, B(1) is bonded in a trigonal planar geometry to one O(2), one O(4), and one O(5) atom. In the second B site, B(2) is bonded to one O(1), one O(2), one O(3), and one O(6) atom to form BO4 tetrahedra that share  a cornercorner with one B(2)O4 tetrahedra,  a cornercorner with one B(3)O4 tetrahedra, and  a cornercorner with one P(1)O4 tetrahedra. In the third B site, B(3) is bonded to two equivalent O(3) and two equivalent O(4) atoms to form corner-sharing BO4 tetrahedra. P(1) is bonded to two equivalent O(6) and two equivalent O(7) atoms to form PO4 tetrahedra that share corners with two equivalent B(2)O4 tetrahedra. H(1) is bonded in a single-bond geometry to one K(2) and one O(5) atom. There are seven inequivalent O sites. In the first O site, O(4) is bonded in a distorted bent 120 degrees geometry to one K(1), one K(2), one B(1), and one B(3) atom. In the second O site, O(5) is bonded in a water-like geometry to one K(1), one K(2), one B(1), and one H(1) atom. In the third O site, O(6) is bonded in a distorted bent 120 degrees geometry to one K(1), one K(2), one B(2), and one P(1) atom. In the fourth O site, O(7) is bonded in a 3-coordinate geometry to one K(1), one K(2), and one P(1) atom. In the fifth O site, O(1) is bonded in a bent 120 degrees geometry to two equivalent K(1) and two equivalent B(2) atoms. In the sixth O site, O(2) is bonded in a bent 120 degrees geometry to two equivalent K(1), one B(1), and one B(2) atom. In the seventh O site, O(3) is bonded in a bent 120 degrees geometry to one K(1), one K(2), one B(2), and one B(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
