      Unusual Luminescence Properties of Heterometallic REE Terephthalates

      Aleksei Y. Grishko, Valentina V. Utochnikova, Aleksei A. Averin, Andrei V. Mironov and Natalia P. Kuzmina

      Article first published online: 5 MAR 2015 | DOI: 10.1002/ejic.201403071

      The quantum yield (QY) of bimetallic terephthalates EuxM1–x(BDC)3/2(H2O)2 (M = Y, Gd; x > 0.05) remains constant (ca. 27 %) upon dilution of Eu3+ with nonluminescent Y3+ or Gd3+. This behavior, unusual for coordination compounds, is ascribed to the ability of the BDC2– environment to accumulate and transfer energy to Eu3+ ions, which sequentially emit several photons after a single excitation.

      Compounds Mg8–xMx(BN2)2N4 were prepared by solid-state reaction of MgCl2, Li3(BN2), and AlN for M = Al, and of Mg3N2, BN, and Si3N4 for M = Si. Their crystal structures were refined from powder X-ray diffraction data with the space group Requation imagem for M = Al, Si, and P21/c for M = Si. Eu(II)-doped Mg8–xMx(BN2)2N4 show broad band emissions in the visible region of the spectrum (λex = 320 nm).

      Thumbnail image of graphical abstract

      A series of iron(II) dicarbonyls are prepared from neutral Schiff base (NNS) ligands. These “phosphine-free” complexes are extremely temperature- and light-sensitive and somewhat like the active site of mono-[Fe] hydrogenase. The Fe(CO)2-bound methylpyridine unit in [(MeNNS)Fe(CO)2Br]+ may represent a “snapshot” of an intermediate during the biogenesis of the Fe–C(=O)acyl-containing active site.

      Nanocomposite photocatalysts CdS/g-C3N4 with different ratios of CdS and graphitic carbon nitride are described as high-performance photocatalysts for environmental remediation. The very stable and recyclable photocatalysts exhibit greatly enhanced photocatalytic activity under visible-light irradiation. Synergistic effects between CdS and g-C3N4 led to efficient separation of charge carriers.

      Cuttings and Couplings: The reactions of 1,4-bis(diphenylphosphanyl)but-2-yne with [Cp2Ti(η2-Me3SiC2SiMe3)] have been investigated. An initial alkyne coupling reaction led to a metallacyclopentadiene. Thermal treatment then led to an allene complex by a 1,3-H shift in the coordinated alkyne. In addition, a highly unusual complex with a Ti–H–P bridge was obtained by phosphorylation of the alkyne.

      Thumbnail image of graphical abstract

      M06-2X computational results reveal that Mes*P=C=E14(tBu)Tip compounds contain both P=C and C=E14 double bonds in nature. Moreover, this theoretical work suggests that the smaller the atomic number of the group 14 element, E14, in the heteroallenic –P=C=E14< molecule, the more kinetically and thermodynamically stable is its heteroallenic –P=C=E14< species towards various chemical reactions.

      New amine-bis(phenolato)cobalt(II) complexes were synthesized and employed in the coupling and copolymerization of carbon dioxide and epoxides. In combination with DMAP, complex 3 enabled poly(cyclohexene) carbonate generation. End-group analysis found DMAP and methoxy terminated polymer chains due to chain-transfer and the active species for CHO/CO2 copolymerization was found to be CoII.

The complexes have similar spectral and electrochemical properties, which are consistent with the results of a theoretical study.

    2. Gold Complexes

      Customized Buchwald-Type Phosphines Bearing an “Inverted” Pyrimidinium Betaine as an Aryl Group Surrogate – Synthesis and Coordination Chemistry with Gold(I)

      Ludovik Noël-Duchesneau, Noël Lugan, Guy Lavigne, Agnès Labande and Vincent César

      Article first published online: 18 FEB 2015 | DOI: 10.1002/ejic.201403205

      The attachment of a pyrimidinium betaine at the ortho position of one of the aryl groups of a triarylphosphine is proposed as a means to diversify the already well-documented palette of Buchwald-type phosphines. The structure of a gold complex reveals that the malonic carbon center that acts as the linker also weakly interacts with the gold center.

      A mixture of CdS and ZnS was prepared in unmodified and organically modified montmorillonite. The products showed emission bands owing to both CdS and ZnS. The blueshift of absorption onsets and the increase in PL intensity were caused by the confinement effect. CdS and ZnS formed separately in different interlayer spaces (segregation).

      An imidazolium salt containing an alkynyl group was synthesized in three steps in order to functionalize nanomaterials by means of CuAAC and Sonogashira reactions. For instance, a nona-azido dendritic core could be “clicked” with the alkynyl-containing imidazolium salt. The resulting dendrimer allows the stabilization of palladium nanoparticles that are active in the Suzuki–Miyaura cross-coupling reaction.

      Zr2PTe2 decomposes along a homogeneity range up to Zr2.5PTe2 by partial filling of the van der Waals gap in the Bi2STe2 structure type. In the consecutive high-temperature decomposition step, “Zr2PTe” is formed. The new phase adopts the structural motif of the binary phases ZrTe and ZrTe2 and tolerates a deficit in the cation position and a mixed occupation of the anions (Zr1.95P0.84Te1.16).
