The reactivity of a redox-active thorium(IV) complex with CH₃I and Me₃SiI is shown to be divergent. This is a rare example of the use of redox-active ligands with the actinides.

To find new coordination and supramolecular assemblies, the structure inducer anions [ZnCl₄]^2– and [CdCl₄]^2– were introduced into alkali metal/pentacyclohexanocucurbit[5]uril (alkali-PCyHQ[5]) systems. These anions did not show the typical “honeycomb effect”, but played the role of linkers in the construction of alkali-PCyHQ[5]-based supramolecular chains.

Chiral phenanthro-annulated imidazolium salts were prepared from 9,10-phenanthrenequinone and 1-phenylethylamine and converted to N-heterocyclic carbenes. Ag^I complexes were obtained by reaction of the imidazolium salts with Ag₂O and used for transmetalation with [RuCl₂(C₆H₆)]₂. Both the Ag^I and the Ru^II complexes showed restricted flexibility in solution.

A new structure type containing layers parallel to (001) built up from Si₃O₁₀ groups and Co₂O₁₀ dimers was determined to be the trisilicate CoEu₂Si₃O₁₀. Light violet monoclinic crystals were obtained by using a high-temperature flux-growth method.

Zintl-type P₇^3– complexes were synthesized from direct activation of P₄ by lanthanum and lutetium naphthalene complexes. The P₇^3– complexes showed fluxional behavior dependent on the rare-earth metal.
