      Metallodithiolene non-innocence is explored in [Mo4+O(iPr2Pipdt)2Cl][PF6] (Pipdt: N,N′-piperazine-2,3-dithione), which possesses a piperazine ring as an integral part of the dithiolene ligand and displays unusual spectroscopic features for a formally reduced MoIV–dithiolene complex. The electronic structure of the ligand can be described in valence bond terms as a resonance hybrid of dithione and dizwitterionic dithiolene.

    1. Bioorganometallic Chemistry

      Preparation and Biological Evaluation of Di-Hetero-Organometallic-Containing PNA Bioconjugates (pages 5471–5478)

      Gilles Gasser, Sebastian Neumann, Ingo Ott, Michael Seitz, Rolf Heumann and Nils Metzler-Nolte

      Version of Record online: 24 NOV 2011 | DOI: 10.1002/ejic.201100734

      Thumbnail image of graphical abstract

      The first two examples of di-hetero-organometallic-containing PNA oligomers have been prepared by the stepwise addition, on a solid support, of two different organometallic complexes to a single peptide nucleic acid oligomer. The products were characterized and their biological activity investigated.

    2. Turn-On Fluorescent Probes

      Naphthaldehyde–Urea/Thiourea Conjugates as Turn-On Fluorescent Probes for Al3+ Based on Restricted C=N Isomerization (pages 5479–5485)

      Debabrata Maity and T. Govindaraju

      Version of Record online: 22 NOV 2011 | DOI: 10.1002/ejic.201100772

      Thumbnail image of graphical abstract

      Two signal transduction mechanisms,namely, chelation-enhanced fluorescence and restricted C=N isomerization, have been exploited to design naphthaldehyde–carbonohydrazone (NC) and naphthaldehyde–thiocarbonohydrazone (NTC) Schiff base ligands as turn-on fluorescent chemosensors for aluminum(III) ions. Al3+ can be detected in the presence of most of the competing metal ions by using NC and NTC.

    3. Ferrimagnetic Oxyphosphate

      Crystal Growth and Structure of the New Ferrimagnetic Oxyphosphate PbFe3O(PO4)3 (pages 5486–5495)

      Hassan El Hafid, Matias Velázquez, Olivier Pérez, Abdelaziz El Jazouli, Alain Pautrat, Rodolphe Decourt, Philippe Veber, Oudomsack Viraphong and Claude Delmas

      Version of Record online: 10 NOV 2011 | DOI: 10.1002/ejic.201100815

      Thumbnail image of graphical abstract

      A new oxyphosphate, PbFe3O(PO4)3, has been discovered and its structure has been characterized by single-crystal XRD. Direct-current (DC) magnetic susceptibility and specific heat measurements performed on single crystals revealed an unusual sequence of second-order ferromagnetic-like phase transitions. Alternating-current (AC) magnetic susceptibility measurements suggest glass-like dynamics.

    4. Silyl-Molybdenum Complexes

      Synthesis of Silyl–Molybdenum Complexes Connected by a 1,1′-Metallocenylene Unit and Their Electrochemical Properties (pages 5496–5501)

      Masumi Itazaki, Akio Ichimura and Hiroshi Nakazawa

      Version of Record online: 8 NOV 2011 | DOI: 10.1002/ejic.201100867

      Thumbnail image of graphical abstract

      Demethanative Mo–Si bond formation was attained in the photoreaction of [Cp*Mo(CO)3(Me)] with ferrocene, which had one or two dimethylsilyl group(s). The electrochemical properties of these complexes are explained by cyclic voltammetry.

    5. Cd Coordination Compounds

      New Cd Thio- and Selenocyanato Coordination Compounds and Their Impact on the Structures and Reactivity of Their Paramagnetic Counterparts (pages 5502–5511)

      Jan Boeckmann, Inke Jeß, Thorben Reinert and Christian Näther

      Version of Record online: 10 NOV 2011 | DOI: 10.1002/ejic.201100745

      Thumbnail image of graphical abstract

      The crystal structures and thermal degradation behaviour of new CdII thiocyanato and selenocyanato coordination compounds are reported. The latter act as structural models for their paramagnetic counterparts.

    6. Aminopyridinates

      Titanium Complexes Stabilized by Bulky Electron-Rich Aminopyridinates and Their Application in Ethylene and Styrene Polymerization (pages 5512–5522)

      Muhammad Hafeez, Winfried P. Kretschmer and Rhett Kempe

      Version of Record online: 10 NOV 2011 | DOI: 10.1002/ejic.201100843

      Thumbnail image of graphical abstract

      Titanium complexes stabilized by bulky and electron-rich aminopyridinates were synthesized, structurally characterized, and investigated for use in ethylene and styrene polymerizations. The electron-donating ability by the ligand was increased by the introduction of a second amine group. The ligand can be made in a variety of forms, extending the list of available monoanionic bidentate nitrogen ligands.

    7. Phosphinous Acid Tautomerism

      Investigations of the Tautomeric Equilibria between Phosphane Oxides and Their Corresponding Phosphinous Acids Bearing Electron-Withdrawing Perfluoroaryl Groups (pages 5523–5529)

      Boris Kurscheid, Waldemar Wiebe, Beate Neumann, Hans-Georg Stammler and Berthold Hoge

      Version of Record online: 15 NOV 2011 | DOI: 10.1002/ejic.201100984

      Thumbnail image of graphical abstract

      The solvent-dependent tautomeric equilibria between secondary phosphane oxides and their corresponding phosphinous acids bearing electron-withdrawing fluoroaryl groups is reported.

    8. Magnesium Complexes

      Magnesium Complexes Containing η1- and η3-Pyrrolyl or Ketiminato Ligands: Synthesis, Structural Investigation and ϵ-Caprolactone Ring-Opening Polymerisation (pages 5530–5537)

      Li-Feng Hsueh, Nien-Tsu Chuang, Cheng-Yuan Lee, Amitabha Datta, Jui-Hsien Huang and Ting-Yu Lee

      Version of Record online: 17 NOV 2011 | DOI: 10.1002/ejic.201100827

      Thumbnail image of graphical abstract

      A series of dimeric magnesium derivatives containing substituted pyrrolyl or ketiminato ligands was synthesised and the compounds were evaluated as catalytic precursors. The complexes show moderate reactivity towards the ring opening polymerisation of ϵ-caprolactone in dichloromethane or tetrahydrofuran.

    9. Bioinorganic Chemistry

      Cell Cycle Arrest, Cytotoxicity, Apoptosis, DNA-Binding, Photocleavage, and Antioxidant Activity of Octahedral Ruthenium(II) Complexes (pages 5538–5547)

      Hong-Liang Huang, Zheng-Zheng Li, Zhen-Hua Liang and Yun-Jun Liu

      Version of Record online: 10 NOV 2011 | DOI: 10.1002/ejic.201100848

      Thumbnail image of graphical abstract

      The synthesis, structure, DNA binding, cytotoxicity, apoptosis, cell cycle arrest, and antioxidant activity of ruthenium(II) complexes 1, 2, and 3 are reported. These complexes can effectively induce apoptosis of BEL-7402 cells. These results obtained from the cell cycle arrest indicated that the antiproliferative mechanism induced by complex 3 on MG-63 cells was G0/G1 phase arrest.

    10. Organyloxozirconium Hydridoborates

      Triorganyl- and Diorganyloxozirconium Hydridoborates – Synthesis and Structures (pages 5548–5557)

      Jörg Knizek, Heinrich Nöth and Martin Schmidt-Amelunxen

      Version of Record online: 21 NOV 2011 | DOI: 10.1002/ejic.201100548

      Thumbnail image of graphical abstract

      Compounds of the type [(RO)4–nZr(BH4)n] were obtained from the reaction of(RO)4Zr (R = Bu, Et) with H3B·THF or that of (RO)4–nZrCln(n = 1, 2; R = tBu3C, tBu3Si) with LiBH4. Boryl group exchange with H2BC8H14 leads to (RO)4Zr(H2BC8H14)n with agostic Zr–H–B bonding when n = 1, whereas a symmetric ZrH2B compound results when n = 2.

    11. Potential Hydroacylation Catalysts

      Exploring (Ph2PCH2CH2)2E Ligand Space (E = O, S, PPh) in RhI Alkene Complexes as Potential Hydroacylation Catalysts (pages 5558–5565)
