New mixed κN,κS mono- and tri-armed bidentate ligands, characterized by a pyridinyl/sulfinyl upcoming arrangement, have been efficiently prepared and fully characterized including by single-crystal X-ray diffraction. The successful chelation of square planar platinum(II) complexes opens the way to promising applications in the preparation of supramolecular organometallic frameworks.

The effects of size, pressure and interactions on 3D spin crossover systems within the framework of an Ising-like model are discussed.

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.
