      The cover picture shows a photograph of a plastic crystal, demonstrating the unusual appearance that these materials can have compared to traditional crystalline salts. The figure also shows the structure of the anti- and syn-isomers of the carbamoylcyano(nitroso)methanide (ccnm) anion. J. Pringle and co-workers report the use of this anion for the development of a new family of ionic liquids and organic ionic plastic crystals in their Full Paper on page 486 ff. The presence of both isomers within the plastic crystals is hypothesized to contribute to the plasticity and solid state conductivity of the materials.

      “One of the interesting outcomes of our research into the ccnm anion was the idea that the presence of a small amount of a second structural isomer of the anion could enhance the plasticity of a material.”

      This and more about the story behind the cover in the Cover Profile and about the research itself on p. 486ff.

      Making a stand: By means of in situ reduction and self-assembly at an unconventional liquid–liquid interface, free-standing ultrathin cobalt nanosheets (CoNs) consisting of nanosized Co clusters were successfully synthesized (see figure). The as-prepared CoNs display ferromagnetic behavior and a large thermal irreversibility. This strategy has been used also in the synthesis of Fe and Ni nanosheets.

      Plastic fantastic: The first use of the carbamoylcyano(nitroso)methanide anion for the synthesis of ionic liquids produces crystal structures that depend strongly on the nature of the cation. The organic ionic plastic crystals made using this anion display good solid-state ionic conductivities, consistent with the increasing interest in this type of material as new solid-state electrolytes.

      IL effects: A self-assembled mesoporous polyoxometalate (POM) with coral-shaped morphology was obtained by pairing Keggin POM anions with newly designed dihydroxy-tethered guanidinium cations of an ionic liquid (IL). Enhancement of the heterogeneous catalytic activity in epoxidation is explained by a unique substrate–solvent–catalyst synergistic mechanism (see figure).

      High-octane action: Isobutane/2-butene alkylation was achieved using an hydrogen chloride gas-promoted, chloroaluminate ionic liquid catalyst in a discontinuous stirred tank reactor. Introducing the HCl additive led to high activity and selectivity in the production of desired trimethylpentanes (TMPs); figure also shows undesired secondary products (C5-C7, dimethylhexanes (DMHs), C9+). Additionally, deactivation of the ionic liquid catalyst was easily avoided.
