      Metal polypyridyl complexes are widely studied in coordination chemistry and have been employed in a wide range of applications, from catalysis to chemical biology. However, their use as potential anticancer agents has not been fully explored. This review highlights recent examples of metal polypyridyl complexes studied for their enzyme-inhibition and cytotoxicity properties.

      The title inclusion complex was characterized by various techniques, including powder and single-crystal XRD. Using the structural model derived from these data as a starting point, DFT calculations led to a model of the crystal structure with 2:1 (host/guest) and 2:2 adducts. Encapsulation of the ferrocene derivative in β-cyclodextrin enhances its antitumor activity towards a breast adenocarcinoma line.

    2. Anion Sensing

      Anion-Sensitive 2,4-Dinitrophenylhydrazone-Containing Terpyridine Derivative and Its Platinum Chloride Complex (pages 4964–4969)

      Bingguang Zhang, Yunjing Li and Wenfang Sun

      Version of Record online: 10 OCT 2011 | DOI: 10.1002/ejic.201100537

      Thumbnail image of graphical abstract

      Terpyridine derivative 1, bearing 2,4-dinitrophenylhydrazone, and its platinum chloride complex 2 exhibit drastic color change as well as quenching of emission intensity and triplet transient absorption upon addition of F, AcO, or H2PO4 anions. Deprotonation of the hydrazone NH group is demonstrated to be the mechanism for the anion sensing.

    3. Diorgano Dichalcogenide Adducts

      Syntheses and Structures of Two Dimethyl Diselenide–Diiodine Adducts and the First Well Characterized Diorgano Disulfide–Nitrosonium Adduct (pages 4970–4977)

      Birgit Mueller, Teemu T. Takaluoma, Risto S. Laitinen and Konrad Seppelt

      Version of Record online: 27 SEP 2011 | DOI: 10.1002/ejic.201100620

      Thumbnail image of graphical abstract

      Two new dimethyl diselenide–iodine adducts have been synthesized as well as the first diorgano disulfide–nitrosonium adduct. Crystal structures and theoretical analysis (DFT) of the reaction of the NO+ cation with R2S2 and the di-neo-pentyl disulfide nitrosonium charge transfer adduct are presented.

    4. Lanthanide Coordination Polymers

      Brilliant Triboluminescence of a Lanthanide Coordination Polymer with Low-Vibrational-Frequency and Non-Centrosymmetric Structural Networks (pages 4978–4984)

      Yasuchika Hasegawa, Ryo Hieda, Kohei Miyata, Tetsuya Nakagawa and Tsuyoshi Kawai

      Version of Record online: 5 OCT 2011 | DOI: 10.1002/ejic.201100688

      We report on characteristic triboluminescence form a europium(III) coordination polymer crystal with non-centrosymmetric Cc structure suitable for piezoelectricity, shown in the figure. Triboluminescence is observed upon breaking, even at ambient temperature and in daylight. The remarkable triboluminescence phenomenon and geometrical structure of lanthanide coordination polymer are demonstrated.

    5. Structural Flexibility of MOFs

      Structural parameters of a row of coordination polymers gradually varied depending on the temperature or size of solvent molecules in the voids. This can be considered as a model of changes occurring at desolvation of the polymers or adsorption of guests. Sorption capacity of these compounds is of the order methanol < ethanol < n-hexane < n-octane. This is consistent with hydrophobic channels.

    6. Bridged Iron(III) Dimers

      Synthesis, Crystal Structure, and Magnetic Properties of a Very Rare Double μ-1,1-Azido- and a μ-1,1-(OMe)-Bridged FeIII Dimer Containing a N,N,O-Donor Tridentate Schiff Base Ligand (pages 4993–4999)

      Subrata Naiya, Michael G. B. Drew, Carmen Diaz, Joan Ribas and Ashutosh Ghosh

      Version of Record online: 11 OCT 2011 | DOI: 10.1002/ejic.201100552

      Thumbnail image of graphical abstract

      A very rare μ-1,1-azido-bridged and a μ-OMe-bridged dinuclear FeIII compound with a tridentate N,N,O-donor Schiff base have been synthesized and characterized structurally. The former is only the third example of μ-1,1-azido bridges in FeIII. The variable-temperature magnetic studies show that the former is ferromagnetically and the latter antiferromagneticallycoupled.

      A (10,3)-d metal-organic framework, [Mn2(pdtd)2(H2O)4]n·5nH2O (1), containing the asymmetrical 3-(2-pyridyl)-5,6-diphenyl-1,2,4-triazine-P,P′-disulfonate ligand (pdtd) was constructed. XRD analysis revealed that 1 is an acentric structure possessing exposed uncoordinated nitrogen atoms within helical cavities. 1 exhibits multifunctionality: nonlinear optical activity, CO2 sorption, and magnetic coupling.

    8. Silylene Chemistry

      Reactions of Stable Amidinate Chlorosilylene and [1+4]-Oxidative Addition of N-Heterocyclic Silylene with N-Benzylideneaniline (pages 5006–5013)

      Anukul Jana, Ramachandran Azhakar, Sankaranarayana Pillai Sarish, Prinson P. Samuel, Herbert W. Roesky, Carola Schulzke and Debasis Koley

      Version of Record online: 10 OCT 2011 | DOI: 10.1002/ejic.201100661

      The reaction of PhC(NtBu)2SiCl (L) withN2O afforded the trimer {PhC(NtBu)2Si(O)Cl}3 (1), containing a Si3O3 six-membered ring. Treatment of L with B(C6F5)3 and 9-BBN {9-borobicyclo[3.3.1]nonane} yielded the chlorosilylene–boron adducts B(C6F5)3 (2) and 9-BBN (3). The reaction of CH{(C=CH2)(CMe)(2,6-iPr2C6H3N)2}Si (L′) with N-benzylideneaniline afforded the [1+4]-cycloaddition product 4.

    9. Rigid Ligands

      Bulky and Modular 3,3′-Bipyrazoles as Ligands: Synthesis, Characterization, and Catalytic Activity of Pd Complexes (pages 5014–5024)

      Markus J. Spallek, Skrollan Stockinger, Richard Goddard, Frank Rominger and Oliver Trapp

      Version of Record online: 21 SEP 2011 | DOI: 10.1002/ejic.201100694

      Thumbnail image of graphical abstract

      A sterically bulky 3,3′-bipyrazole ligand class was synthesized in excellent yields using camphor as a building block. The highly modular nature of the system gave rise to a series of 11 new ligands with tunable steric and electronic properties. The derived catalysts with increasing electron-donating properties revealed higher conversions in Cu-free Wacker oxidations of terminal alkenes.

    10. Backbonding in NHC Complexes

      How Important Is Backbonding in Metal Complexes Containing N-Heterocyclic Carbenes? Structural and NBO Analysis (pages 5025–5035)

      Aleix Comas-Vives and Jeremy N. Harvey

      Version of Record online: 10 OCT 2011 | DOI: 10.1002/ejic.201100721

      Thumbnail image of graphical abstract

      DFT calculations have been used to analyze metal-to-ligand backbonding in a range of model transition metal complexes of N-heterocyclic carbenes. Two new methods of analysis have been introduced. The first is structural, and the second uses the perturbative natural bond orbital (NBO) method. Both methods lead to the firm conclusion that backbonding is significant in these compounds.

    11. Multifunctional Hydrazone Ligands

      Dinuclear, Tetranuclear and Chain (MnII, CoII) Complexes of Multifunctional Hydrazone Ligands – Structural and Magnetic Studies (pages 5036–5042)

      Peter J. Bettle, Louise N. Dawe, Muhammad U. Anwar and Laurence K. Thompson

      Version of Record online: 7 OCT 2011 | DOI: 10.1002/ejic.201100746

      Thumbnail image of graphical abstract

      Multifunctional polytopic hydrazone ligands form polymetallic complexes with μ-O (hydrazone, carboxylate) and μ-N,N (triazole) bridging, leading to spin–spin interactions between the metal centres with examples of antiferromagnetic and ferromagnetic exchange.

    12. Manganese Cluster Compounds

      A New Family of Homo- and Heterometallic Manganese Complexes at High Oxidation States Derived from the Oxidation of MnII with CeIV: Syntheses, Structures, and Magnetic Properties (pages 5043–5053)

      Cheng-Bing Ma, Ming-Qiang Hu, Hui Chen, Chang-Neng Chen and Qiu-Tian Liu

      Version of Record online: 10 OCT 2011 | DOI: 10.1002/ejic.201100719

      Thumbnail image of graphical abstract

      Four Mn or mixed Mn/Ce clusters at high oxidation states were prepared by the reaction of Mn2+ salts where (NH4)2[Ce(NO3)6] was used as an oxidizing agent. These complexes possess inorganic cores that have topologies that range from the rhomb, the triangle, and the nonplanar loop to the trigonal bipyramid. The four complexes possess distinctly different magnetic properties.
