Zn3GaB6PO12 crystallizes in the trigonal R3m space group. Zn(1) is bonded to one P(1), one O(3), and two equivalent O(1) atoms to form distorted ZnPO3 tetrahedra that share  a cornercorner with one Ga(1)PO3 tetrahedra, corners with two equivalent Zn(1)PO3 tetrahedra, and corners with six equivalent B(1)O4 tetrahedra. Ga(1) is bonded to one P(1) and three equivalent O(2) atoms to form distorted GaPO3 tetrahedra that share corners with three equivalent Zn(1)PO3 tetrahedra and corners with six equivalent B(1)O4 tetrahedra. B(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form BO4 tetrahedra that share  a cornercorner with one Ga(1)PO3 tetrahedra, corners with three equivalent Zn(1)PO3 tetrahedra, and corners with four equivalent B(1)O4 tetrahedra. P(1) is bonded in a tetrahedral geometry to three equivalent Zn(1) and one Ga(1) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Zn(1) and two equivalent B(1) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to one Ga(1) and two equivalent B(1) atoms. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Zn(1) and two equivalent B(1) atoms.
