      The cover picture shows an eruption of a volcano, which symbolically corresponds to the role of the volcanic “iron–sulfur world” and the Wächtershäuser model in the chemoautotrophic hypothesis of the origin of life, in which polysulfide species play an important role. Further details on polysulfide moieties that appear to easily adopt chiral arrangements in platinum complexes can be found in the article by W. K. Rybak et al. on p. 3675 ff. The foreground of the picture shows a figurative representation of the conglomerate crystallization-induced asymmetric synthesis that is operating autocatalytically without any chiral auxiliary reagents. The asymmetric synthesis is triggered by exploiting seeds of the enantiomeric product and by applying vigorous stirring of the reaction mixture.

    1. Asymmetric Synthesis

      Crystallization-Induced Asymmetric Synthesis of Nonracemic Platinum(IV) Polysulfide Tris(chelate) Complexes (pages 3675–3679)

      Witold K. Rybak, Agata Cymbaluk, Miłosz Siczek and Janusz Skonieczny

      The anionic complex [Pt(S5)3]2– is obtained in a nonracemic form by a newly recognized mechanism, the conglomerate crystallization-induced asymmetric synthesis (CIAS). With vigorous stirring, the synthesis is operating autocatalytic. This demonstrates the usefulness of chiral crystalline conglomerates in asymmetric synthesis.

      The synthesis and structural properties of Cu(II) and Ni(II) cyclidene complexes shows that the 16-membered macrocycles can adopt Z- or U-shape conformations. The Z-shape Cu complexes are flexible enough to stabilize the metal ions in the uncommon oxidation states +1 and +3. Structural modifications allow fine-tuning of the properties of the complexes for specific applications.

      MesnacnacZnH {Mesnacnac = [(2,4,6-Me3C6H2)NC(Me)]2CH} reacts with 4-(dimethylamino)pyridine (dmap) upon adduct formation, whereas reactions with (tBuN)2C, tBuNCS and CHO proceed with insertion into the Zn–H bond. In contrast, Me3SiN3 was found to react with MesnacnacZnH with the formation of MesnacnacZn(N3), which forms an azido-bridged dimer in the solid state.

      Multipod Pd nanocrystals were synthesized on the gram scale by means of a simple solid–liquid phase reaction route. A multistep formation mechanism that includes digestive ripening, oriented attachment, and a fusion process is proposed. This Pd nanostructure exhibits excellent electrocatalytic activity and long-term stability toward the oxidation of formic acid.

      Four [Ir(ppy)2(N∧N)][PF6] (N∧N = 4,6-diphenyl-2,2′-bipyridine derivative) complexes have been synthesized and characterized. In solution, the complexes are short-lived emitters with emission maxima between 600 and 635 nm; the solid-state emission spectra are similar. The performances of the complexes as electroluminescent components in LECs have been evaluated.
