Cerium iron sulfide, Ce₃Fe_1.94S₇

In Ce₃Fe_1.94S₇, which adopts the Ce₆Al_3.33S₁₄ structure type, isolated FeS₄ tetrahedra, all pointing in the same direction, are stacked along the threefold rotation axes. Chains of face-sharing FeS₆ octahedra are connected by CeS₇₊₁ bicapped trigonal prisms.

Lithium and beryllium hypophosphites

The LiH₂PO₂ and Be(H₂PO₂)₂ structures consist of layers of cations bridged by hypophosphite anions. The cations are tetrahedrally coordinated by oxygen.

β-LiMoO₂(AsO₄)

A new non-symmetrical form of LiMoO₂(AsO₄) has been synthesized by a solid-state reaction method. It crystallizes in monoclinic space group P2₁. The three-dimensional open framework is built up of corner-sharing AsO₄ tetrahedra and MoO₆ octahedra containing tunnels running along the a axis, where Li⁺ cations are located.
