      The cover picture shows a cosmic phenomenon which applies mutatis mutandis to the chemistry described within this article. Similar to the absorbed star, the appropriate silver(I) carboxylate as silver source and 2,2′-spirobi[4H-1,3,2-benzodioxasiline] as the specific twin monomer afford the corresponding hybrid material through twin polymerization. Within this process, highly porous materials of type Ag@C (red) and Ag@SiO2 (blue) are obtained via organic–inorganic nanocomposites. The material beams represent HAADF-STEM images of the porous silver-containing materials. The background photo is from Fotolia (Copyright Li-Bro/fotolia.com). We acknowledge graphic designer Zhenxing Xu for incorporating our chemical structures and TEM images into the picture. Details are discussed in the Short Communication by H. Lang et al. on p. 3161 ff. For more on the story behind the cover research, see the Cover Profile.

    6. Porphyrin Distortions

      Electronic Origin of Out-of-Plane Distortions in Porphyrins (pages 3200–3207)

      Muthu P. Austeria, Pattath D. Pancharatna and Musiri M. Balakrishnarajan

      Article first published online: 4 JUN 2014 | DOI: 10.1002/ejic.201402157

      Thumbnail image of graphical abstract

      Out-of-plane distortions in porphyrins are found to be electronic in origin. The lowest unoccupied molecular orbitals (LUMOs) of various metalloporphyrins show the mixing of a porphyrin a2u molecular orbital with dinline image (a1g), dxy (b2g) and dinline image (b1g) orbitals to exhibit doming, ruffling and saddling, respectively. These distortions that retain aromaticity are attributed to σ–π mixing.

    7. Imaging Agents

      Zn2+-Responsive Bimodal Magnetic Resonance Imaging and Fluorescence Imaging Agents and Their Interaction with Human Serum Albumin (pages 3208–3215)

      Ying-Qi Xu, Jian Luo and Zhong-Ning Chen

      Article first published online: 5 JUN 2014 | DOI: 10.1002/ejic.201402197

      Thumbnail image of graphical abstract

      Gadolinium(III)-based bimodal magnetic resonance imaging (MRI) and fluorescence imaging agents exhibit strong coordination or noncovalent interactions with human serum albumin (HSA) and, thus, induce remarkable relaxivity enhancement and significant turn-on luminescence.

    8. Borasiloxanes

      Ru0-Catalyzed Coupling of Vinylboronates with Silanols, Disilanols, and Disiloxanediols: a Selective Route to Borasiloxanes (pages 3216–3220)

      Dawid Frąckowiak, Jędrzej Walkowiak, Grzegorz Hreczycho and Bogdan Marciniec

      Article first published online: 3 JUN 2014 | DOI: 10.1002/ejic.201402212

      Thumbnail image of graphical abstract

      A new, selective approach to borasiloxanes through catalytic O-borylation was developed. Vinylboronates are coupled with silanols, silanediols, and siloxanediols, which yield borasiloxanes as the only products with the evolution of ethylene. A mechanism for this Ru3(CO)12-catalyzed transformation is also proposed.

    9. Coordination Polymers

      Modulating the MII/Pyrimidine-4,6-dicarboxylato System by Metal, Solvent and Temperature Variation (pages 3221–3234)

      Javier Cepeda and Sonia Pérez-Yáñez

      Article first published online: 12 JUN 2014 | DOI: 10.1002/ejic.201402269

      Thumbnail image of graphical abstract

      The pyrimidine-4,6-dicarboxilato ligand preferentially renders planar 1D motifs when coordinating to first-row divalent metal ions. This structural limitation has been avoided by focusing on three approaches that share a common aim: to modulate the coordination sphere by replacing/eliminating solvent molecules. A complete thermal characterisation and steric hindrance analysis is reported.

      Mianzeng Zhong, Zhongming Wei, Xiuqing Meng, Fengmin Wu and Jingbo Li

      Article first published online: 3 JUN 2014 | DOI: 10.1002/ejic.201402079

      Thumbnail image of graphical abstract

      Flowerlike MoS2 microspheres are used as a precursor for the preparation of 2H-MoS2 nanoparticles, MoS2/α-MoO3 heterojunctions, and α-MoO3 nanoplates. The growth mechanism is studied in detail. Among the four samples, the MoS2/α-MoO3 heterojunctions and MoS2 microspheres show excellent photocatalytic activity.

    12. Group 13 Compounds

      Structures and Magnetic Properties of Group 13 Metal Tris-O-benzosemiquinonato Complexes (pages 3252–3258)

      Alexandr V. Piskunov, Irina N. Meshcheryakova, Arina V. Maleeva, Artyem S. Bogomyakov, Georgy K. Fukin, Vladimir K. Cherkasov and Gleb A. Abakumov

      Article first published online: 4 JUN 2014 | DOI: 10.1002/ejic.201402116

      Thumbnail image of graphical abstract

      The octahedral coordination polyhedron is characteristic of Al and Ga tris-o-benzosemiquinolates, whereas the analogous In derivatives have trigonal-prismatic configurations. Magnetochemical investigations show that ferromagnetic exchange prevails in Al and Ga compounds. The trigonal-prismatic complexes demonstrate antiferromagnetic behavior.

    13. Acyclic Diaminocarbenes

      Stable N-Phosphanyl Acyclic Diaminocarbenes (pages 3259–3270)

      Anatoliy Marchenko, Georgyi Koidan, Anastasiya Hurieva, Olena Kurpiieva, Yurii Vlasenko, Alexander B. Rozhenko and Aleksandr Kostyuk

      Article first published online: 12 JUN 2014 | DOI: 10.1002/ejic.201402166

      Thumbnail image of graphical abstract

      The deprotonation of PIII N-substituted formamidinium salts afforded a new type of stable acyclic N-phosphanyl-diaminocarbene. The carbenes possess an optimal substitution pattern, deviations from which make them unstable. They transform into C-phosphanylformamidines by a N,C-phosphorus shift, which was studied by quantum chemistry calculations.

    14. Hemiacetal Synthesis

      Copper-Assisted Hemiacetal Synthesis: A CuII Chain Obtained by a One-Step in situ Reaction of Picolinaldehyde (pages 3271–3278)
