GaTaO4 is Hydrophilite-derived structured and crystallizes in the orthorhombic Pna2_1 space group. Ta(1) is bonded to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms to form distorted TaO6 octahedra that share corners with four equivalent Ta(1)O6 octahedra, corners with four equivalent Ga(1)O6 octahedra, and edges with two equivalent Ga(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 49-56°. Ga(1) is bonded to one O(2), one O(3), two equivalent O(1), and two equivalent O(4) atoms to form distorted GaO6 octahedra that share corners with four equivalent Ta(1)O6 octahedra, corners with four equivalent Ga(1)O6 octahedra, and edges with two equivalent Ta(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 49-55°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Ta(1) and two equivalent Ga(1) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Ta(1) and one Ga(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent Ta(1) and one Ga(1) atom. In the fourth O site, O(4) is bonded in a trigonal planar geometry to one Ta(1) and two equivalent Ga(1) atoms.
