The material structure described by BaGaAlO4 crystallizes in the monoclinic C2 space group. Ba(1) is bonded in a 9-coordinate geometry to one O(2), one O(4), two equivalent O(3), two equivalent O(5), and three equivalent O(1) atoms. Ga(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form GaO4 tetrahedra that share  a cornercorner with one Al(1)O4 tetrahedra and corners with three equivalent Ga(1)O4 tetrahedra. Al(1) is bonded to one O(1), one O(4), and two equivalent O(5) atoms to form AlO4 tetrahedra that share  a cornercorner with one Ga(1)O4 tetrahedra and corners with three equivalent Al(1)O4 tetrahedra. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to three equivalent Ba(1), one Ga(1), and one Al(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to two equivalent Ba(1) and two equivalent Ga(1) atoms. In the third O site, O(3) is bonded in a 4-coordinate geometry to two equivalent Ba(1) and two equivalent Ga(1) atoms. In the fourth O site, O(4) is bonded in a 2-coordinate geometry to two equivalent Ba(1) and two equivalent Al(1) atoms. In the fifth O site, O(5) is bonded in a 2-coordinate geometry to two equivalent Ba(1) and two equivalent Al(1) atoms. is represented by the CIF card [CIF]
