Synthetic aenigmatite analog Na₂(Mn_5.26Na_0.74)Ge₆O₂₀: structure and crystal chemical considerations

The crystal structure of a synthetic aenigmatite-type Na–Mn germanate has been determined and compared with the structures of other naturally occurring and synthetic members of the aenigmatite mineral group.

The diphyllosilicate Rb₂(VO)₂[Si₈O₁₉]

The structure of the title compound consists of silicate double layers separated by [V₂O₈]⁸⁻ dimers with Rb⁺ cations inter­leaved. It is the first example of an anhydrous diphyllosilicate containing vanadium(IV).

The disordered cluster compound CaMo₅(Mo_0.38Ti_0.62)O₁₀

The title compound is isomorphous with the Sr and Eu analogs. The main structural feature is the occurrence of edge-shared bioctahedral Mo₁₀ clusters, and monocapped and bicapped Mo₁₀ clusters forming, respectively, Mo₁₁ and Mo₁₂ clusters, which co-exist randomly in the structure.
