The reactions of (dpp-BIAN)Zn-Zn(dpp-BIAN) (1) with PhC CH and of [(dpp-BIAN)Zn(mu-I)](2) (2) with potassium hydride yield the binuclear complexes [(dpp-BIAN)Zn(mu-C CPh)](2) (3) and [(dpp-BlAN)Zn(mu-H)](2) (4), respectively (dpp-BIAN = 1,2-bis[(2,6-diisopropylphenyl)imino] acenaphthene). Complex 3 is also obtained by thermal dehydrogenation of [dpp-BIAN(H)]Zn-(C CPh) (5), which in turn can be prepared by reacting ZnI2, with equimolar amounts of [dpp-BIAN(H)]Na and PhC CNa. The paramagnetic compounds 3 and 4 have been characterized by ESR spectroscopy; the diamagnetic complex 5, by H-1 NMR spectroscopy. The molecular structures of 3 and 4 have been determined by single-crystal X-ray diffraction. The electronic structure of complex 4 has been examined by DFT.

Decomposition of zinc (1-hydroxyethylidene)diphosphonate induced by aliphatic amines and ammonia. Molecular structures of ammonium (1-hydroxyethylidene)diphosphonates

V. V. Semenov, N. Zolotareva, O. Novikova, B. Petrov, N. M. Lazarev, G. K. Fukin, A. Cherkasov, E. N. Razov

Summary: It has been found that the sparingly soluble zinc (1-hydroxyethylidene)diphosphonate can rapidly dissolve into aqueous solution when exposed to ammonia or aliphatic amines that do not contain hydrophilic groups, forming ammonium derivatives. Among these derivatives, those based on triethylamine, tert-butylamine, or di-n-butylamine have good solubility, while those based on hexamethylenediamine and ammonia have poor solubility.

Marina A. Katkova, Galina S. Zabrodina, Roman. Rumyantcev, Grigory Yu. Zhigulin, Maria S. Muravyeva, Andrey S. Shavyrin, Dmitriy G. Sheven, Sergey Yu. Ketkov

Summary: The increased interest in water-soluble aminohydroximate Ln(III)-Cu(II) metallacrowns (MC) is driven by their fascinating structural chemistry, diverse properties, and simple synthesis. We investigated the water-soluble praseodymium (III) alaninehydroximate complex Pr(H2O)4[15-MCCu(II)Alaha-5]center dot 3Cl (1) as an effective chiral lanthanide shift reagent for NMR analysis of biologically relevant (R/S)-mandelate (MA) anions in water. The enantiomers R-MA and S-MA can be easily distinguished in the presence of small amounts of MC 1 by the 1H NMR signals of multiple protons with an enantiomeric shift difference (Delta Delta delta) ranging from 0.06 ppm to 0.31 ppm. Additionally, the possibility of MA coordination to the metallacrown was investigated using ESI-MS technique and Density Functional Theory modeling.

W18O49 Nanowire Arrays for Plasmonic Photodetector with Electromediated Broadband Photoresponse

Yongan Zhu, Wei Lu, Tongtong Gu, Xin Gao, Naisen Yu, Sergey Yu. Ketkov, Zhenyi Zhang

Summary: We developed a plasmonic semiconductor photodetector based on W18O49 nanowire array (NWA) to achieve a tunable broadband photodetector. By adjusting the plasmonic absorption intensity of the W18O49 NWA through manipulating the free electron density with an external voltage, the responsivity and detectivity of the photodetector in the visible-NIR region were significantly increased. The proposed strategy of using low-cost nonmetallic plasmonic nanostructures offers a promising way to construct broadband-tunable photodetectors.

Intramolecular charge transfer in bulky diazabutadiene-M(II)-catecholate chromophores (M = Ni, Co): A role of a molecular geometry

Kira I. Pashanova, Irina Ershova, Ilya A. Yakushev, Irina N. Meshcheryakova, Maxim Arsenyev, Alexandr Piskunov

Summary: Two monomeric heteroleptic charge transfer (CT) complexes, NiII(3,6-Cat)(DADdipp) (1) and CoII(3,6-Cat)(DADdipp) (2), were synthesized using a two-step synthetic procedure. Complex 1 exhibits a low energy ligand-to-ligand charge transfer (LL'CT), resulting in a NIR NiII chromophore with high light absorption and sensitivity to solvent polarity. Complex 2, on the other hand, shows a significant change in CT properties and a decrease in absorptivity due to the bulky ligands. The electrochemical behavior of the complexes is determined by the differences in coordination geometry and the involvement of the metal center in redox transitions.

An investigation into the Bronsted acidity of the perfluorinated alkoxy silanes {(F3C)3CO}3SiH and {(F6C5)3CO}2Si(Cl)H

Felix Feige, Lorraine A. Malaspina, Florian Kleemiss, Julius F. Koegel, Sergey Ketkov, Emanuel Hupf, Simon Grabowsky, Jens Beckmann

Summary: The perfluorinated alkoxy silanes were synthesized and fully characterized. However, attempts to deprotonate them to form the conjugate silanide ions failed due to the exceptionally short and strong Si-H bonds. In the solid state, the Si-H units do not participate in any intermolecular interactions, and the crystal packing is dominated by exceptionally short and strong F...F interactions. The cohesive energies are solely attributed to London dispersion interactions, similar to noble gas crystal structures.

Summary: The reactivity of phenanthro-[9,10]-(1,3,2)-diazadiphospholenes towards iron triad carbonyls has been investigated. Diphospholenes react with cobalt octacarbonyl and diiron nonacarbonyl as phosphinyl radicals. The reaction with nickel carbonyl involves the initial coordination of diphospholenes to the metal ion as Lewis bases. The obtained compounds were characterized by NMR and IR spectroscopy, and their structure was determined using X-ray structural analysis. DFT computational studies examined the bonding nature in the new compounds.
