摘要

The first nickelacarborane with closo-nido structure [10 ',11 '-(Py)(2)-3,9 '-Ni(1,2-C2B9H11)(7 ',8 '-C2B8H8)] was isolated from the reaction of nickel(IV) bis(dicarbollide) with pyridine. The molecular structure of this complex was determined by single crystal X-ray diffraction. The nickel atom is a common vertex for the closo-NiC2B9 cluster and the nido-NC2B8 cluster where it is located together with carbon atoms in the open NiC2B2 pentagonal face. It is assumed that its formation proceeds through the nucleophile-induced removal of the B(6)H vertex followed by rearrangement of the forming 11-vertex cluster, which most likely proceeds through a sequence of closing and opening reactions.

Reversible Transition between Discrete and 1D Infinite Architectures: A Temperature-Responsive Cu(I) Complex with a Flexible Disilane-Bridged Bis(pyridine) Ligand

Yongjin Zhao, Toyotaka Nakae, Satoshi Takeya, Mineyuki Hattori, Daisuke Saito, Masako Kato, Yoshinori Ohmasa, Shun Sato, Osamu Yamamuro, Tomasz Galica, Eiji Nishibori, Shiori Kobayashi, Tomohiro Seki, Teppei Yamada, Yoshinori Yamanoi

Summary: A thermoresponsive structural change based on a disilane-bridged bis(pyridine) ligand and CuI is reported. Single-crystal X-ray analysis revealed two polymorphs in the Cu(I) complex: an octanuclear copper(I) complex at 20 degrees C and a 1D staircase copper(I) polymer complex at -173 degrees C. The formation of these polymorphs is attributed to the flexibility of the ligand. Cooling the sample from -10 degrees C to -170 degrees C resulted in Cu-I bond formation. DSC, VT-PXRD, and VT-photoluminescence measurements clarified the temperature-induced phase transition progression, indicating a reversible temperature-controlled crystal-to-crystal phase transition. Crystal cracking during single-crystal to single-crystal transitions between these polymorphic forms was observed using a high-speed camera.

Bis(5-chloroquinolin-8-olato)-bis(pyridine)-cobalt(II) as new catalytic material

Joanna Drzezdzon, Celina Mokwa, Artur Sikorski, Patrycja Parnicka, Adriana Zaleska-Medynska, Jacek Malinowski, Magdalena Kwiatkowska, Barbara Gawdzik, Dagmara Jacewicz

Summary: Nowadays, there are studies on the design and synthesis of new catalysts for olefin oligomerization and polymerization, with non-toxic metals and high catalytic activities. Transition metal complex compounds, such as Fe(II), Cr(III), and Zr(II), that contain pyridine or quinoline ligands have been found to exhibit moderate catalytic activity in ethylene and propylene polymerizations. In this study, a new cobalt(II) complex compound with bis(5-chloroquinolin-8-olato)-bis(pyridine) ligands was synthesized and tested for its catalytic activity in reactions of 2-chloro-2-propen-1-ol and norbornene oligomerizations. The results showed that the activated bis(5-chloroquinolin-8-olato)-bis(pyridine)-cobalt(II) catalyst can promote the formation of oligomers in nitrogen atmosphere, at atmospheric pressure, and at room temperature, demonstrating moderate catalytic activity in norbornene oligomerization and low catalytic activity in 2-chloro-2-propen-1-ol oligomerization.

Kazuhiro Hirano, Hideki Yamauchi, Naoya Nakahara, Kazuo Kinoshita, Maki Yamaguchi, Shigeru Takemori

Summary: This study showed that eccentric contractions induce strain-specific structural changes at the molecular level in rat plantaris muscle. Different frequencies of eccentric contraction stimulation resulted in various effects on the myofilament lattice and protein phosphorylation. Eccentric contractions were more efficient in phosphorylating signaling proteins compared to isometric contractions, and high-frequency stimulation caused a significant decrease in some protein reflection intensities.

How substituents at boron atoms affect the CH-acidity and the electron-withdrawing effect of the ortho-carborane cage: A close look on the 1H NMR spectra

Igor B. Sivaev, Sergey A. Anufriev, Akim V. Shmalko

Summary: Based on the data of 1H NMR spectra, the effect of various substituents at boron atoms in different positions of the ortho-carborane cage on its CH-acidity and the electron-withdrawing effect upon substitution at the carbon atom is discussed. It is found that the introduction of chlorine atoms slightly reduces the CH-acidity, whereas the introduction of bromine and iodine atoms significantly increases the CH-acidity compared to the parent orthocarborane. The introduction of halogen atoms to the boron atoms bound to both carbon atoms leads to a significant increase in the CH-acidity, regardless of halogen electronegativity. However, in the case of polychlorinated derivatives of ortho-carborane, the total effect of the substituent covers the decrease in CH-acidity when the first halogen atoms are introduced into specific positions. The introduction of alkyl substituents reduces the CH-acidity, while the introduction of aryl substituents has the opposite effect.
