      Hollow titania spheres with anatase and brookite phases were selectively fabricated by hydrothermal treatment of hollow capsules formed by a polyionic water-soluble Ti complex and a cationic polyelectrolyte.

    2. Solvent-Modulated Luminescence

      Synthesis and Characterisation of Thiophene-Functionalised Lanthanoid Diketonate Clusters with Solvent-Modulated Europium Luminescence (pages 3273–3282)

      Philip C. Andrews, Glen B. Deacon, William J. Gee, Peter C. Junk and Aron Urbatsch

      Article first published online: 1 JUN 2012 | DOI: 10.1002/ejic.201200105

      Thumbnail image of graphical abstract

      Two tetranuclear (Ln = Nd, Eu) and one pentanuclear (Ln = Er) lanthanoid hydroxido cage clusters have been isolated ligated by a thiophene-containing diketonato ligand. Assessment of the luminescent properties of the europium cluster at 25 °C identified a motif prone to thermal quenching; however, incremental addition of selected coordinating solvents was found to promote luminescence at 25 °C.

    3. Porous Metal Oxides

      Mesoporous Al2O3 by Nanocasting: Relationship between Crystallinity and Mesoscopic Order (pages 3283–3288)

      Stefanie Haffer, Christian Weinberger and Michael Tiemann

      Article first published online: 1 JUN 2012 | DOI: 10.1002/ejic.201200131

      Thumbnail image of graphical abstract

      Nanocasting is a versatile method to create mesoporous alumina (Al2O3) with a cubic pore architecture. The pores of a mesoporous carbon matrix are filled with a liquid melt of aluminum nitrate, followed by conversion to aluminum hydroxide by NH3 vapor treatment and subsequent calcination. The NH3 treatment is investigated in detail as it affects the crystallinity and the porosity of the products.

    4. Iridium(IV) Complexes

      A Stable Iridium(IV) Complex Containing the Kläui Tripodal Ligand [Co(η5-C5H5){P(O)(OEt)2}3] (pages 3289–3295)

      Ho-Fai Ip, Yat-Ming So, Hung Kay Lee, Ian D. Williams and Wa-Hung Leung

      Article first published online: 31 MAY 2012 | DOI: 10.1002/ejic.201200138

      Thumbnail image of graphical abstract

      Treatment of [Ir(LOEt)Cl2(COE)] (LOEt = [Co(η5-C5H5){P(O)(OEt)2}3]) with ozone/air in CH2Cl2 affords a stable IrIV complex, [Ir(LOEt)Cl3], which exhibits an EPR signal (CH2Cl2, 4 K) with g = 2.06 and 1.65 and an IrIV/IrIII redox couple of ca. 0 V vs. Cp2Fe+/0.

    5. Ammonothermal Synthesis

      Ammonothermal Synthesis of Alkali N,N′-Bis(aminocarbonyl)phosphorodiamidates M[PO2(NHCONH2)2] (M = Na, K, Rb) (pages 3296–3301)

      Eva Wirnhier, Ruth Deborah Boller and Wolfgang Schnick

      Article first published online: 6 JUN 2012 | DOI: 10.1002/ejic.201200209

      Thumbnail image of graphical abstract

      Ammonothermal treatment of biuretooxophosphates prevented decomposition of the precursor into phosphates and gaseous CNH(O) compounds at higher temperatures according to Le Chatelier's principle and yielded the hitherto unknown alkaliN,N′-bis(aminocarbonyl)phosphorodiamidates M[PO2(NHCONH2)2] (M = Na, K, Rb).

    6. Self-Assembly

      Bridging Pseudohalides in Palladacycles as a Source of Different Assemblies (pages 3302–3307)

      Marta Arroyo, Patricia Gómez-Iglesias, José Santos Melero, Daniel Schildbach, Christian Unkelbach, Carsten Strohmann and Fernando Villafañe

      Article first published online: 1 JUN 2012 | DOI: 10.1002/ejic.201200247

      Thumbnail image of graphical abstract

      Coordination of pseudohalides to the soft metal center of a silapalladacycle leads to different bridging modes depending on the pseudohalide. With cyanide, a molecular square is formed, which in solution is in equilibrium with the corresponding triangular species.

    7. Sugar Coordination Complexes

      Metal Complexation of a D-Ribose-Based Ligand Decoded by Experimental and Theoretical Studies (pages 3308–3319)

      Federico Cisnetti, Jean-Didier Maréchal, Magali Nicaise, Régis Guillot, Michel Desmadril, François Lambert and Clotilde Policar

      Article first published online: 29 MAY 2012 | DOI: 10.1002/ejic.201200322

      Thumbnail image of graphical abstract

      A new sugar-derived ligand, with its coordination site embedded in a pyranoside cycle in the chair conformation, has been designed. Its transition-metal complexes were characterized by experimental and complexation methods and revealed a dramatic impact of the preorganization and complementarity of the carbohydrate scaffold on the metal binding.

    8. Iridium Catalysis

      Structure–Activity Relationship in the Iridium-Catalyzed Isomerization of Primary Allylic Alcohols (pages 3320–3330)

      Luca Mantilli, David Gérard, Céline Besnard and Clément Mazet

      Article first published online: 6 JUN 2012 | DOI: 10.1002/ejic.201200369

      Thumbnail image of graphical abstract

      Crabtree catalyst analogues [(Cy3P)(4-Z-C6H5N)Ir(cod)]·BArF {BArF = tetrakis[3,5-bis(trifluoromethyl)phenyl]borate}have been prepared by an efficient one-pot protocol. Excellent correlations between analytical data and both thermodynamic and kinetic parameters point to the possibility of qualitatively predicting the activity of these complexes in the isomerization of primary allylic alcohols.

    9. Oxidorhenium Cocatalysts

      Synthesis, Characterisation and Catalytic Application of Oxidorhenium Complexes Bearing H-Spirophosphorane Ligands (pages 3331–3341)

      Anna Skarżyńska, Miłosz Siczek and Jarosław M. Sobczak

      Article first published online: 6 JUN 2012 | DOI: 10.1002/ejic.201200062

      Thumbnail image of graphical abstract

      Rhenium complexes bearing H-spirophosphorane ligands have been synthesised and employed as cocatalysts for the oxidation of aldehydes with molecular oxygen.

    10. Ordered Perovskites

      Long-Range Order in Layered Perovskite Salts – Structure and Magnetic Properties of [(CH3)2CHCH2NH3]2CuX4 (X = Cl, Br) (pages 3342–3348)

      Roger D. Willett, Carlos J. Gómez-García and Brendan Twamley

      Article first published online: 31 MAY 2012 | DOI: 10.1002/ejic.201101200

      Thumbnail image of graphical abstract

      Hybrid organic–inorganic layered perovskite copper halides [(CH3)2CHCH2NH3]2CuX4, (X = Cl and Br) present 3d ordering. The Cl salt has the typical antiferrodistortive arrangement and presents 3d ferromagnetic ordering at 6.5 K. For the Br salt, a decorated ribbon structure is proposed to explain ferrimagnetic ordering at 12.2 K and canted 3d ordering between the decorated ribbons at 6.8 K.

    11. Supramolecular Frameworks

      Chiral Supramolecular Frameworks Based on Chiral Metallocycles: Crystal Structures and Photophysical Properties (pages 3349–3360)

      By the self-assembly of the synthesized purely chiral terpyridyl ligand (S)-2{4-[2,6-bis(pyridin-2-yl)pyridin-4-yl]benzylamino}propanoic acid (H2ptpy) with metal ions, a new class of purely chiral metal–organic frameworks built from the chiral metallocyclic subunits formed by two chiral (Hptpy) anions that bridge two metal ions in a head-to-tail style was prepared and characterized.
