ZnB(PO4)2NH4 crystallizes in the triclinic P-1 space group. The structure consists of two ammonium molecules inside a ZnB(PO4)2 framework. In the ZnB(PO4)2 framework, Zn(1) is bonded to one O(2), one O(3), one O(5), and one O(7) atom to form ZnO4 tetrahedra that share corners with two equivalent P(1)O4 tetrahedra and corners with two equivalent P(2)O4 tetrahedra.
