(NH4)[UO2(HSeO3)(SeO3)] contains layers of UO7 pentagonal bipyramids and selenite groups, with hydrogen bonds involving the ammonium ions connecting adjacent layers.

The loosely packed structure of Cs4YbCl7 consists of layers of close-packed YbCl63− octahedra and Cs+ ions separated by layers containing the other half of the Cs+ ions and the remaining Cl ion, which is sixfold disordered.

The metallic framework of Sr4Ga3Mo26O48 is based on infinite Mo7–Mo10–Mo7 chains and quasi-isolated monocapped octahedral Mo7 clusters which are interconnected through O atoms. The Sr2+ ions have environments derived from cuboctahedra and the Ga3+ ions are approximately tetrahedrally or octahedrally

LiCo2P3O10 and LiNi2P3O10 contain staggered chains of CoIIO6 and NiIIO6 octahedra, respectively, cross-linked by edge-sharing LiO6 groups. The P3O10 groups have both staggered and eclipsed conformations.

The {[Mo8O26(MoO4)]6−}n anion in (NH4)6[Mo9O30].5H2O has a zigzag chain structure in which two adjacent Mo8O26 moieties are linked by an MoO4 tetrahedron.
