Detail of the extended structure of (I) showing a Zr2As3O18 `lantern' motif of Zr1 and Zr2 octa­hedra linked by three As1 tetra­hedra via atoms O2 and O3. In (I), this motif has crystallographically imposed threefold symmetry about a rotation axis passing through the zirconium atoms. Symmetry codes: (i) 1 − y, 1 + x − y, z; (ii) y − x, 1 − x, z.
