The structure described by TaAsO4 crystallizes in the monoclinic Pc 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 edge-sharing TaO6 octahedra. As(1) is bonded in a distorted T-shaped geometry to one O(1), one O(3), and one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Ta(1) and one As(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to two equivalent Ta(1) atoms. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent Ta(1) and one As(1) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one Ta(1) and one As(1) atom. is represented by the CIF card [CIF]
