      The cover picture shows a series of cationic iridium complexes synthesized in our lab with emission spanning the visible color spectrum. A general scheme of a cationic heteroleptic iridium complex incorporating two anionic cyclometalating (C∧N) and one neutral ancillary (L∧X) ligands is shown in the middle at the bottom of the picture. On either side of the arrow at the top are the HOMO and LUMO for the archetype complex [Ir(ppy)2(bpy)]+. Details are presented in the Microreveiw by S. Ladouceur and E. Zysman-Colman on p. 2985 ff. For more on the story behind the cover research, see the Cover Profile.

      A Comprehensive Survey of Cationic Iridium(III) Complexes Bearing Nontraditional Ligand Chelation Motifs (pages 2985–3007)

      Sébastien Ladouceur and Eli Zysman-Colman

      Article first published online: 18 APR 2013 | DOI: 10.1002/ejic.201300171

      Thumbnail image of graphical abstract

      This Microreview summarizes the optoelectronic properties of luminescent cationic iridium complexes bearing nontraditional ligand motifs with generalized structure [(C∧N)2Ir(L∧X)]+, in which C∧N is a cyclometalating ligand and L∧X is a bidentate neutral ancillary ligand, with the goal of elucidating structure–property trends. Their use in applications such as photosensitizers for solar fuels and as luminophores in light-emitting electrochemical cells is also discussed.

      Heterobimetallic complexes Pt–Ru (1) and Ru–Pt (2) were constructed from directional bis(terpyridine) ruthenium(II) and bipyridinedichloroplatinum(II) moieties. The photophysical properties of 1 and 2 as well as their responses to one-electron reduction (thermal and photochemical) were elucidated by EPR spectroscopy, DFT calculations, and Stern–Volmer plots.

      Article first published online: 26 APR 2013 | DOI: 10.1002/ejic.201300118

      Thumbnail image of graphical abstract

      A multifunctional mesoporous silica hybrid is presented, in which the receptor site plays a key role in nucleobase recognition, pH-induced delivery of anticancer agents, and as a metal binding site for Cu2+ ions. The pyridine-containing material selectively recognizes thymidine, is an effective potential drug-carrier system in cancer therapy, and is an efficient adsorbent for Cu2+ removal.

    4. Polyhydride Complexes

      Towards Reagents for Bimetallic Activation Reactions: Polyhydride Complexes with Ru2H3, Ru2ZnH6, and Cu2Ru2H6 Cores (pages 3039–3048)

      Article first published online: 26 APR 2013 | DOI: 10.1002/ejic.201300233

      Thumbnail image of graphical abstract

      Di-, tri-, and tetranuclear polyhydride complexes with a fac-[RuH3(PPh3)3] anion are accessible by salt metathesis of [Li(thf)3{Ru(μ-H)3(PPh3)3}] (1) with [Cp*RuCl]4, ZnCl2, and CuCl(SMe2). Complexes 24 have been characterized by X-ray crystallography and spectroscopic techniques. DFT calculations support the structural analyses and examine the influence of the London dispersion interactions.

      Mechanistic Studies on the Reaction of Nitrocobalamin with Glutathione: Kinetic Evidence for Formation of an Aquacobalamin Intermediate (pages 3049–3053)

      David T. Walker, Rohan S. Dassanayake, Kamille A. Garcia, Riya Mukherjee and Nicola E. Brasch

      Article first published online: 29 APR 2013 | DOI: 10.1002/ejic.201300254

      Thumbnail image of graphical abstract

      Kinetic studies on the reaction of nitrocobalamin (NO2Cbl) with glutathione show that glutathionylcobalamin (GSCbl) is formed via an aquacobalamin (H2OCbl+) intermediate. This reaction pathway is demonstrated by independently determining individual rate constants for each step.

    6. Absolute Brønsted Acidity

      The Al(ORF)3/H2O/Phosphane [RF = C(CF3)3] System – Protonation of Phosphanes and Absolute Brønsted Acidity (pages 3054–3062)

      Anne Kraft, Josephine Possart, Harald Scherer, Jennifer Beck, Daniel Himmel and Ingo Krossing

      Article first published online: 10 MAY 2013 | DOI: 10.1002/ejic.201300031

      Thumbnail image of graphical abstract

      Small donor ligands such as Ph2MeP, Ph3P, Ph3As, or even H2O form classical donor–acceptor adducts with the Lewis superacid Al(ORF)3 [RF = C(CF3)3]. FLP-like (FLP = frustrated Lewis pair) combinations of this Lewis acid, phosphanes, and water then lead to [HPR3]+ and two new weakly coordinating anions [HOAl(ORF)3] and [(FRO)3Al(μ-OH)Al(ORF)3]. The absolute acidity of H2O–Al(ORF)3 is evaluated.

      A mixed-ligand nickel–organic framework has been made that has a 3-c uninodal 2D + 2D [RIGHTWARDS ARROW] 3D polycatenated net. It can catalyse almost all types of olefinic substrates with equal efficiency and be used for several cycles without loss of any catalytic activity.

    10. Biomimetics

      Dinuclear Cobalt(II) Complexes as Metallo-β-lactamase Mimics (pages 3082–3089)

      Lena J. Daumann, James A. Larrabee, Peter Comba, Gerhard Schenk and Lawrence R. Gahan

      Article first published online: 30 APR 2013 | DOI: 10.1002/ejic.201300280

      Thumbnail image of graphical abstract

      Two dinuclear CoII complexes were tested for their ability to hydrolyze β-lactam substrates. The [Co2(CO2EtH2L1)(CH3COO)2]+ complex is reactive towards nitrocefin and penicillin, whereas [Co2(CO2EtL2)(CH3COO)2]+ is unreactive. The difference between the two complexes is due to the presence of an alkoxide in the former.

      Tuning the Hydrolytic Properties of Half-Sandwich-Type Organometallic Cations in Aqueous Solution (pages 3090–3100)

      Linda Bíró, Attila J. Godó, Zsolt Bihari, Eugenio Garribba and Péter Buglyó

      Article first published online: 5 MAY 2013 | DOI: 10.1002/ejic.201201527

      The hydrolytic properties of half-sandwich [M(η6-arene)(H2O)3]2+ (M = Ru, Os; η6-arene = benzene, toluene, 1-methyl-4-isopropylbenzene, 1,3,5-triisopropylbenzene) or [Ir(η5-Cp*)(H2O)3]2+ (Cp* = pentamethylcyclopentadienyl) cations can be tuned by the proper selection of the arene system and by modification of the metal ion to make them more resistant to hydrolysis.

    12. Magnetic Coordination Polymers

      A series of pybox ligands were used as effective coligands to construct four azide–copper low-dimensional coordination polymers. Two of these polymers possess similar 1D infinite azide–copper hexagonal tapes and the other two possess a very interesting enantiopure 2D honeycomb layer structure. Magnetic studies revealed the weak ferromagnetic characters of these complexes.
