Abstract

In the title compound, trizinc(II) diarsenite or trizinc(II) bis­[trioxidoarsenate(III)], the constituent polyhedra that make up the structure are very distorted ZnO4 tetra­hedra and AsO3 trigonal pyramids. These species fuse together to generate a three-dimensional network containing unusual edge-sharing tetra­hedra, with a ZnZn separation of 2.903 (3) Å. The structure also features eight-ring pseudo-channels occupied by the AsIII lone pairs of electrons. The title compound is a polymorph of the mineral reinerite, which also features edge-shared ZnO4 tetra­hedra.
