There are three inequivalent As sites. In the first As site, As(1) is bonded to one O(1), one O(10), one O(3), and one O(7) atom to form AsO4 tetrahedra that share corners with two equivalent Co(1)O6 octahedra, corners with three equivalent Co(2)O6 octahedra, and  a cornercorner with one As(3)O4 tetrahedra.

The corner-sharing octahedral tilt angles range from 49-64°. In the third As site, As(3) is bonded to one O(10), one O(4), one O(5), and one O(8) atom to form AsO4 tetrahedra that share  a cornercorner with one Co(1)O6 octahedra,  a cornercorner with one Co(2)O6 octahedra,  a cornercorner with one As(1)O4 tetrahedra, and  a cornercorner with one As(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 46-60°. There are ten inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Co(1), one Co(2), and one As(1) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one Co(1), one Co(2), and one As(2) atom.

In the seventh O site, O(7) is bonded in a 3-coordinate geometry to one Na(1), one Co(1), and one As(1) atom. In the eighth O site, O(8) is bonded in a distorted trigonal non-coplanar geometry to one Na(1), one Co(1), and one As(3) atom. In the ninth O site, O(9) is bonded in a 4-coordinate geometry to one Na(1), two equivalent Co(1), and one As(2) atom.
