The crystal structure described by TaOPO4 crystallizes in the tetragonal P4/n space group. Ta(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form distorted TaO6 octahedra that share corners with two equivalent Ta(1)O6 octahedra and corners with four equivalent P(1)O4 tetrahedra. The corner-sharing octahedra are not tilted. P(1) is bonded to four equivalent O(2) atoms to form PO4 tetrahedra that share corners with four equivalent Ta(1)O6 octahedra. The corner-sharing octahedral tilt angles are 29°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to two equivalent Ta(1) atoms. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Ta(1) and one P(1) atom. is represented by the CIF file [CIF]
