TaZn2SbO6 crystallizes in the monoclinic P2_1/m space group. Ta(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form TaO6 octahedra that share corners with two equivalent Ta(1)O6 octahedra, corners with four equivalent Sb(1)O6 octahedra, corners with four equivalent Zn(2)O4 tetrahedra, and corners with four equivalent Zn(1)O4 trigonal pyramids.
