    1. Non-Oxido Mixed-Valence MnII6MnIII4 Cluster with Benzoate, Triethanolamine and Phosphonate Bridging Ligands (pages 3097–3101)

      Catherine Dendrinou-Samara, Christopher A. Muryn, Floriana Tuna and Richard E. P. Winpenny

      Article first published online: 11 MAR 2010 | DOI: 10.1002/ejic.200901227

      {[K3Mn10(PhCOO)10(PhPO3)2(Htea)6](PhCOO)·6MeCN}n (1) was prepared by a combination of triethanolamine and phosphonates with manganese benzoate chemistry. The resulting {Mn10} cage can be regarded as an analogue of 24-metallacrown-10, acting as a host for three potassium ions, while it crystallises as a cation; benzoate anions link the cages into a 1D polymer within the crystal. The room-temperature value of 1 is very close to the spin-only value of 38.25 cm3 mol–1 K expected for six MnII and four MnIII ions.

    2. Trapped Radical Cation

      Trapped in a Complex: the 1,2,4,5-Tetrakis(tetramethylguanidino)benzene Radical Cation (ttmgb) with a Bisallylic Structure (pages 3102–3108)

      Christine Trumm, Olaf Hübner, Elisabeth Kaifer and Hans-Jörg Himmel

      Article first published online: 27 MAY 2010 | DOI: 10.1002/ejic.201000118

      Isolation by Complexation: The radicalcation ttmgb+· [ttmgb = 1,2,4,5-tetrakis(tetramethylguanidino)benzene] can only be stabilized by complexation. It is formed as an intermediate in oxidation of ttmgb to ttmgb2+ with CuII and features a bisallyl-type structure.

    3. DNA Cleavage

      Synthesis, Crystal Structure, DNA Binding, and Hydrolytic Cleavage Activity of a Manganese(II) Complex (pages 3109–3116)

      Jing Qian, Xiao-Fang Ma, Hai-Zhen Xu, Jin-Lei Tian, Jing Shang, Yuan Zhang and Shi-Ping Yan

      Article first published online: 27 MAY 2010 | DOI: 10.1002/ejic.200901231

      Thumbnail image of graphical abstract

      A new trinuclear manganese(II) complex has been synthesized and structurally characterized by X-ray crystallography. The variable temperature-dependent susceptibility measurement (2–300 K) of 1 reveals a weak antiferromagnetic interaction between the manganese ions through the bridging dichlorido ligands.

    4. Phosphacyclic Compounds

      Unexpected Oxidative Dimerisations of a Cyclopentadienyl-Phosphane – Formation of Unprecedented, Structurally Remarkable Phosphacyclic Compounds (pages 3117–3124)

      Crispin Lichtenberg, Michael Elfferding and Jörg Sundermeyer

      Article first published online: 2 JUN 2010 | DOI: 10.1002/ejic.200901267

      Thumbnail image of graphical abstract

      The reactions of PMe2(C5HMe4) (1) with PPh3CH2X+ X (X = Cl, Br. I) and with CH2I2 were studied. The potential electrophiles act as oxidising agents initiating theunexpected reaction pathway of oxidative dimerisations in all four cases. Single-crystal XRD analyses of two of these structurally remarkable products are reported.

    5. Cocrystallized Tetranuclear Complexes

      Syntheses, Structures and Magnetic Properties of Trinuclear CuIIMIICuII (M = Cu, Ni, Co and Fe) and Tetranuclear [2×1+1×2] CuIIMnII–2CuII Complexes Derived from a Compartmental Ligand: The Schiff Base 3-Methoxysalicylaldehyde Diamine Can also Stabilize a Cocrystal (pages 3125–3134)

      Arpita Biswas, Meenakshi Ghosh, Pascale Lemoine, Sohini Sarkar, Susanta Hazra and Sasankasekhar Mohanta

      Article first published online: 27 MAY 2010 | DOI: 10.1002/ejic.201000050

      The syntheses, structures and magnetic properties of the monophenoxido-bridged, trinuclear CuIIMIICuII (M = Cu, Ni, Co, Fe) complexes and the tetranuclear [2×1+1×2] cocrystal of the diphenoxido-bridged, dinuclear CuIIMnII and mononuclear CuII moieties from a compartmental ligand are described. The ligand is the [2+1] condensation product of 3-methoxysalicylaldehyde and trans-1,2-diaminocyclohexane.

    6. Water Splitting

      Examination of Water Oxidation by Catalysts Containing Cofacial Metal Sites (pages 3135–3142)

      Derek J. Wasylenko, Chelladurai Ganesamoorthy, Bryan D. Koivisto and Curtis P. Berlinguette

      Article first published online: 27 MAY 2010 | DOI: 10.1002/ejic.201000099

      A series of bimetallic architectures were developed to examine how the distance between two juxtaposed {Ru(tpy)(bpy)Cl}1+ units affect catalytic water oxidation.Despite M···M distances ranging from ca.5–12 Å, each member of the series is shown to catalyze the CeIV-driven oxidation of water. This result suggests that metal cooperativity is not essential to dioxygen bond formation.

    7. Luminescent Dinuclear Complexes

      Dinuclear Complexes of the N2O2 Oxime Chelate Ligand with Zinc(II)–Lanthanide(III) as a Selective Sensitization System for Sm3+ (pages 3143–3152)

      Shigehisa Akine, Fumihiko Utsuno, Takanori Taniguchi and Tatsuya Nabeshima

      Article first published online: 26 MAY 2010 | DOI: 10.1002/ejic.200901243

      Thumbnail image of graphical abstract

      Complexation of an oxime chelate ligand H2L with ZnII and LnIII afforded a series of dimetallic complexes [LZnLn(OAc)3] (Ln = Sm–Lu). The ligand moiety selectively sensitizes the f–f emission of Sm3+; [LZnSm(OAc)3] exhibits a relatively intense red luminescence due to f–f transitions, whereas the complexes [LZnLn(OAc)3] (Ln = Eu, Tb, Dy, etc.) exhibit very weak emission.

    8. Metal String Complexes

      Linear Tetranickel String Complexes with Mixed Supported Ligands and Mixed-Valence Units [Ni2]3+: Synthesis, Crystal Structure, and Magnetic Studies (pages 3153–3159)

      Che-Wei Yeh, Isiah Po-Chun Liu, Rui-Ren Wang, Chen-Yu Yeh, Gene-Hsiang Lee and Shie-Ming Peng

      Article first published online: 2 JUN 2010 | DOI: 10.1002/ejic.201000145

      Thumbnail image of graphical abstract

      Four linear tetranickel string complexes supported by mixed ligands were synthesized and isolated. The crystal structural analysis showed that the mixed-valence [Ni2]3+ unit can possibly be stabilized by only two naphthyridyl groups, which might allow us to modulate the physical properties of metal string complexes by modifying the other two ligands.

    9. Unusual Anion Effects

      Unusual Anion Effects in the Iron-Catalyzed Formation of 3-Hydroxyacrylates from Aromatic Aldehydes and Ethyl Diazoacetate (pages 3160–3166)

      Luis Gonçalo Alves, Georg Dazinger, Luis F. Veiros and Karl Kirchner

      Article first published online: 21 MAY 2010 | DOI: 10.1002/ejic.201000240

      Thumbnail image of graphical abstract

      The complex trans-[Fe(PNP-iPr)(CO)2Cl]X with X = BF4 is an efficient precatalyst for the coupling of aromatic aldehydes with ethyl diazoacetate to afford selectively 3-hydroxyacrylates in up to 90 % yield. This reaction is strongly dependent on the nature of the counterion. With PF6 about 20 % conversion is observed, whereas in the case of NO3, CF3COO, CF3SO3, SbF6, and BAr′4 no reaction takes place. A conceivable mechanism is established by means of DFT/B3LYP calculations.

      Xiang-Lin Meng, Ning Lun, Yong-Qiu Qi, Jian-Qiang Bi, Yong-Xin Qi, Hui-Ling Zhu, Fu-Dong Han, Yu-Jun Bai, Long-Wei Yin and Run-Hua Fan

      Article first published online: 19 MAY 2010 | DOI: 10.1002/ejic.201000260

      Thumbnail image of graphical abstract

      Meshy boron nitride (BN) with a large surface area of 220 m2 g–1 was synthesized by the reaction of NaBH4 and CS(NH2)2, which exhibits strong cathode-luminescence emission, good thermal stability, and oxidation resistance up to 800 °C. The vulcanization behavior of CS(NH2)2 for the cross-linking among borazine molecules is critical for the formation of meshy BN.
