      The cover picture shows X-ray crystal structures contrasting the differences in stacking and coordination geometry of platinum(II) complexes of 4,4’-dimethyl-2,2’-bipyridine and 2-(2’-pyridyl)quinoxaline. The CD spectra emphasise the effect that such structural differences can have upon the electronic properties of the compounds. Fluorescently stained HT29 human colon carcinoma cells make up the background, demonstrating the application of the complexes as anticancer agents. Finally, the Southern Cross refers to the country of origin of this work, while the yellow stars represent our acknowledgement to this journal and the European Union. Details are discussed in the article by J. R. Aldrich-Wright et al. on p. 4167 ff. For more on the story behind the cover research, see the Cover Profile.

      Trinuclear bisphosphine-bridged iron carbonyl clusters are introduced as homogeneous catalysts for proton reduction. Hydrido species form in the presence of acids, and hydrogen is produced electrocatalytically at low overpotential. These electron-rich iron–sulfur clusters are discussed as a promising starting point for the development of photochemical model compounds of iron-based hydrogenases.

    11. Thin-Film Precursors

      Synergistic and Antagonistic Ligand Effects in the Transformation of Silver Compounds of Keto- and Cyano-Functionalised Oximates and Nitronates: A Systematic Study Using Thermal Analysis (pages 4254–4259)

      Rudolf C. Hoffmann and Jörg J. Schneider

      Article first published online: 10 AUG 2015 | DOI: 10.1002/ejic.201500704

      Thumbnail image of graphical abstract

      The thermal decomposition of silver compounds with functionalised oximato and nitronato ligands proceeds by intra- and intermolecular redox reactions and can also involve unexpected rearrangements. The quest for suitable molecular precursors by variation of side groups within the ligands is a delicate matter, but can be facilitated by advanced thermal analysis. The correct combination of moieties can achieve decomposition at low temperatures.
