      The cover picture shows the uptake of organometallic gold(I) N-heterocyclic (NHC) complexes, bearing a fluorescent coumarin moiety, in cancer cells and the resulting anticancer effects. Notably, the most effective compound of the reported series bears the 1-thio-βD-glucose tetraacetate ligand, which may enhance its cellular uptake, therefore making the compound more cytotoxic. Once inside the cells, the gold compound may target the selenoenzyme thioredoxin reductase and induce mitochondrial damage. Details are discussed in the Short Communication by E. Bodio, A. Casini et al. on p. 4532 ff. For more on the story behind the cover research, see the Cover Profile.

    1. On the Investigation of the Droplet–Droplet Interactions of Sodium 1,4-Bis(2-ethylhexyl) Sulfosuccinate Reverse Micelles upon Changing the External Solvent Composition and Their Impact on Gold Nanoparticle Synthesis (Eur. J. Inorg. Chem. 27/2014)

      Article first published online: 22 SEP 2014 | DOI: 10.1002/ejic.201490138

      The inside cover picture shows the high versatility of reverse micelles as nanoreactors. The composition of the nonpolar organic medium has a huge effect on properties such as the interfacial micropolarity, the hydrogen-bonding ability, and the sequestrated water structure of sodium 1,4-bis(2-ethylhexyl)sulfosuccinate (AOT) reverse micelles (RMs). Therefore, not only gold nanoparticles (in n-heptane) but also evidence of subnanometer clusters (in benzene) was obtained by using RMs as nanoreactors. The results are very promising for many applications. Details are discussed in the article by N. M. Correa et al. on p. 2095 ff.

      (Eur. J. Inorg. Chem. 27/2014)

      Article first published online: 22 SEP 2014 | DOI: 10.1002/ejic.201490139

      Thumbnail image of graphical abstract

      The back cover picture highlights Werner's legacy, which is celebrated by coordination chemistry contributions describing observations both in the first coordination sphere, the second coordination sphere and beyond. Specific orbital requirements define the geometry of complexes with Tc–Tc multiple bonds (Poineau et al.), and the binding of tetrathiafulvalene ligands to the DyIII dimer results in a single-molecule magnet (Pointillart et al.). In addition, noncovalent interactions can order a system in layers as found for the organometallic Pd–uracil compound (Moriuchi, Hirao et al.), the ordering can be critical for the resulting spin polarization mechanism in cyanido-bearing CoIII/CoII complexes (Alexandru, Marino, Julve et al.) and for the ability of vapochromic PtII complexes to support water binding in the solid state (Kobayashi and Kato). The background shows a group photo of the delegates taken at the 4th Zing Coordination Chemistry Conference held in Mexico in December 2013 (the background photo is used with permission from Zing Conferences Ltd.). Thanks to Guest Editor Debbie Crans for putting the parts of the composite cover together.

      Modern Coordination Chemistry 100 Years after Werner (pages 4413–4416)

      Debbie C. Crans and Ebbe Nordlander

      Article first published online: 22 SEP 2014 | DOI: 10.1002/ejic.201402826

      Thumbnail image of graphical abstract

      An overview of the papers in this cluster issue is presented. “It is more than 100 years ago that Alfred Werner developed the research that led to the birth of coordination chemistry as we know it today. The consequences of this seminal work continue to evolve, documenting that not only structural and electronic effects but also perhaps, most importantly, the application of coordination chemistry remain as timely and current now as it was back then.”

      Trigonal Bipyramidal or Square Pyramidal Coordination Geometry? Investigating the Most Potent Geometry for Vanadium Phosphatase Inhibitors (pages 4450–4468)

      Debbie C. Crans, Michael L. Tarlton and Craig C. McLauchlan

      Article first published online: 1 AUG 2014 | DOI: 10.1002/ejic.201402306

      Thumbnail image of graphical abstract

      In this microreview, we analyze the five-coordinate geometries (an important factor in phosphoryl group transfer) for a range of VO4X coordination spheres with regard to their structure, considered as square pyramidal or trigonal bipyramidal geometries. We demonstrate that actual differences between the coordination environments are very small and presumably less critical than generally anticipated.

      Article first published online: 22 JUL 2014 | DOI: 10.1002/ejic.201402297

      Thumbnail image of graphical abstract

      Irradiation of ammonium heptamolybdate tetrahydrate soft-oxometalate (SOM) nanorods with UV light leads to their topological transformation into molybdenum blue SOM nanospheres. This transformation is accompanied by a colour change from colourless to blue, which can be exploited for UV sensing. Thus, when a particular threshold amount of UV irradiation is absorbed, the nanorods change colour.

      Article first published online: 15 AUG 2014 | DOI: 10.1002/ejic.201402253

      Thumbnail image of graphical abstract

      Calculating the absolute spin-state energies of metal complexes is a challenge for quantum chemistry. Computing trends is easier, but caution is required. Not all functionals perform equally, and even for the good ones, there are generally outliers. Despite significant progress, the “universal functional” remains elusive.

      A convenient method for the synthesis of a series of chiral [Zn(salen)] [salen = N,N′-bis(salicylidene)ethylenediamine dianion] complexes based on a 1,2-diphenylethanediamine backbone has been developed. These complexes have been used to assemble multinuclear supramolecular assemblies of which the solid-state and solution properties were determined. These chiral [Zn(salen)] complexes hold promise as molecular building blocks with modular characteristics.

      The metal–histidine vibrations of the Cu,Zn-superoxide dismutase enzyme are analyzed by mid- and far-infrared difference spectroscopy. The histidine metal–ligand markers are analyzed and assigned from a combination of experimental and computational data. The contributions of the histidine modes are identified through additional data collected and calculated for labelled samples.

      A series of bis(oxazoline)-copper(I) complexes reversibly bind dioxygen to yield biomimetic μ-η22-peroxo-dicopper(II) species, which represent new functional hemocyanin models. Their kinetics of formation have been studied under cryo conditions, and the complexes have been isolated as surprisingly stable solids. All were investigated by a variety of methods, both in solution and in the solid state.

      Eight complexes of formula [MCl(L)(PTA)] (M = Pd or Pt, L = 5-nitrofuryl-containing thiosemicarbazone ligands, PTA = 1,3,5-triaza-7-phosphaadamantane) were obtained. Most were active in vitro against T. cruzi. The mechanism involves bioreduction and formation of free radical species. All interact with DNA in an intercalative-like manner, but this does not lead to their antichagasic activity.
