The structure described by TaAsO5 crystallizes in the orthorhombic Pnma space group. Ta(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form TaO6 octahedra that share corners with two equivalent Ta(1)O6 octahedra and corners with four equivalent As(1)O4 tetrahedra. The corner-sharing octahedra are not tilted. As(1) is bonded to one O(1), one O(3), and two equivalent O(2) atoms to form AsO4 tetrahedra that share corners with four equivalent Ta(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 14-30°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Ta(1) and one As(1) atom. In the second O site, O(2) is bonded in a linear geometry to one Ta(1) and one As(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Ta(1) and one As(1) atom. In the fourth O site, O(4) is bonded in a linear geometry to two equivalent Ta(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
