Abstract:

Abstract The reaction of Y(NO3)3 · 5H2O and 2,2':6',2"-terpyridine (terpy) in MeCN leads to [Y(N03 )3(terpy)(H2O )] (1) and [Y(N03 )3(terpy)(H2O )] terpy-3MeCN (2) in good yields depending on the isolation conditions. The structures of both complexes were determined by single-crystal X-ray crystallography. The YIII atom in 1 is 9-coordinate and ligation is provided by one terdentate terpy molecule, two chelating nitrates, one monodentate nitrate and one terminal H2O molecule; the coordination polyhedron about the metal may be viewed as a tricapped trigonal prism. The YIII atom in 2 is 10-coord

Abstract The present review covers almost 100 polymeric MFe (M=Li, Na, K, Rb, and Cs) compounds. The metal atoms of group 1 as partners with iron atom build up complex polymeric chains. The iron atoms are found in the oxidation states 0, +2, and +3, of which the oxidation state +3 prevails. The coordination number of the iron atom ranges from 2 to 10 (sandwiched). The coordination sphere about the main group 1 metals varies, ranging from tetrahedral to mostly trigonal bipyramid. There are also higher coordination numbers involved, namely, from 6 to 10. The most common ligand atoms are oxygen a

This review summarizes experimental and theoretical studies of transition metal complexes with two types of novel metal-carbon bonds. One type features complexes with carbones CL2 as ligands, where the carbon(0) atom has two electron lone pairs which engage in double (σ and π) donation to the metal atom [M]⇇CL2. The second part of this review reports complexes which have a neutral carbon atom C as ligand. Carbido complexes with naked carbon atoms may be considered as endpoint of the series [M]-CR3 → [M]-CR2 → [M]-CR → [M]-C. This review includes some work on uranium and cerium complexes, but i

Abstract:

Treatment of [60]fullerene with an organocopper reagent converts one of the pentagons of the fullerene into cyclopentadienyl anion through addition of five organic groups on every peripheral carbon atom surrounding the pentagon. Similar treatment of [70]fullerene afforded indenyl anion through regioselective tri-addition of the organic group. These anionic moieties strongly interact with the remainder of the fullerene p-system, and provide unique opportunity for exploration of organometallic chemistry of a new class of metal cyclopentadienides.

However, the presence of single atoms in traditional nanoparticle-based catalysts remains largely overlooked.

Abstract:

Infrared and Raman spectra of Cu(II) bis(2,4-pentandionate) and Pd(II) bis(2,4-pentandionate) complexes have been measured and interpreted. The coincidence of numerous bands in the IR and Raman spectra has been explained by the isolation effect of the heavy central metal atom which prevents the vibrational interaction of the two ligands in the chelate molecule with each other. An 11-particle model consisting of all the atoms of one ligand (both CH3 groups are taken as the point masses), a central metal atom and two oxygen atoms of the other ligand has been proved to be most adequate for the em

A novel type of purely electromagnetic interaction is proposed, with binding energies and dimensions between chemistry and nuclear.

Abstract:

Optical self-defocusing, characterized by the non-linear refractive index n2, was investigated by the Z-scan technique in water solutions of two porphyrins (PPhs), negatively charged meso-tetrakis(p-sulfonatophenyl)porphyrin ( TPPS 4) and positively charged meso-tetrakis(4-N-methyl-pyridiniumyl)porphyrin ( TMPyP ), in their free base forms and as Fe (III) and Mn (III) complexes. Significant n2 values were observed only for the TMPyP metal complexes, while for the other porphyrins the n2 values were negligible. The effect is explained by the reorientation of the porphyrin molecule due to intera

Abstract:

The structure of the title complex consists of [Ir3(C5Me5)3(L-prolinate)3]3+ complex cations and CF3SO3- anions. Each iridium atom is coordinated in a distorted tetrahedral manner by one cyclopentadienyl group, two carboxylate O atoms and the prolinate N atom. The iridium atoms are bridged by the carboxylate groups. Each of the three stereogenic iridium atoms has the same (S) configuration, i. e. the trimerization of the [Ir(C5Me5)(L-prolinate)]+ fragment occurs with chiral self recognition.

The radial distribution function revealed three distinct peaks assigned to the oxygen, amido carbon (C1, and nitrogen atoms of six planar DMF molecules in the first coordination sphere around the metal atom. The distance from the cobalt atom to each atom (O, C1, N) is 213,299, and 423 pm, respectively. This indicates that the Co-O-C1 bond angle i

The crystal structure of OsPt2(μ-CO)3(CO)2(PPh3)3 has been determined by single-crystal X-ray diffraction techniques.

With two equivalents of the same reagent the binuclear complex 4 is generated, in which the metal atoms are S- and N-bonded. The reaction of 2 equivalents of 1 with [(tetrahydrothiophene)2Au]ClO4 affords the 2:1 complex 5 with the gold atom exclusively S-bonded. The analogous reaction with AgBF4 gives the

The catalytic olefin isomerization reaction is a highly efficient and atom-economic transformation in organic synthesis that has attracted tremendous attention both in academia and industry. Recently, the development of Earth-abundant metal catalysts has received growing interest owing to their wide availability, sustainability, and environmentally benign nature, as well as the unique properties of non-precious metals. This review provides an overview of a broad range of base-metal-catalyzed olefin isomerization reactions categorized according to their different reaction mechanisms.1 Introdu
