The crystal structure described by B3O5NH4 crystallizes in the monoclinic C2/c space group. The structure consists of eight ammonium molecules inside a B3O5 framework. In the B3O5 framework, there are three inequivalent B sites. In the first B site, B(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form corner-sharing BO4 tetrahedra. In the second B site, B(2) is bonded in a trigonal planar geometry to one O(3), one O(4), and one O(5) atom. In the third B site, B(3) is bonded to one O(2), one O(5), and two equivalent O(1) atoms to form a mixture of corner and edge-sharing BO4 tetrahedra. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one B(1) and two equivalent B(3) atoms. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one B(1) and one B(3) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one B(1) and one B(2) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to one B(1) and one B(2) atom. In the fifth O site, O(5) is bonded in a distorted bent 120 degrees geometry to one B(2) and one B(3) atom. is represented by the CIF card [CIF]
