N,N′-(1,4-Phenyl­ene)bis­(4-chloro­butanamide)

The title mol­ecule, C14H18Cl2N2O2, lies on a crystallographic inversion center and the each 4-chloro­butanamide group adopts an anti-staggered conformation. In the crystal, adjacent mol­ecules are linked through N—H⋯O contacts, forming infinite ribbons extending parallel to the a axis

Synthesis and X-ray Characterisation of a New Mixed-valence Trinuclear Iron Cluster

This paper reports on the synthesis of a new trinuclear homometalic mixed-valent iron carboxylate cluster with furan-2-carboxylic acid. The complex with the formula [Fe2IIIFeIIO(C4H3OCOO)6(H2O)3]∙0.5CH3CN•2.25H2O was characterized by X-ray analysis that revealed that the compound crystalizes in the triclinic centrosymmetric group P-1, with the following unit cell parameters: a = 10.2758(6)Å, b = 11.5991(9) Å, c = 19.7349(15) Å, α = 105.060(7)°, β = 94.216(6)°, γ = 101.662(6)°

Synthesis and Characterisation of a Novel Phosphonate Ligand and Its Palladium(II) Coordination Compound

The novel N-(methylene-2-pyridine)-N,N-bis(diethoxyphosphorylmethyl)amine ligand (L) was obtained through a double Kabachnik-Fields reaction, starting from 2-aminomethyl pyridine (2-picolylamine). Based on the L ligand, a new palladium(II) coordination compound [Pd(L)2Cl2] has been synthetized and comprehensively characterized by spectroscopic methods (1H NMR, UV-Vis), ESI mass spectrometry and X-ray crystallography

Synthèse et caractérisation de nouveaux complexes de métaux de transition pour catalyse d'oxydation et la réduction électrolytique des protons

De nos jours, la capacité à synthétiser de nouveaux catalyseurs métallique bioinspirés pour améliorer et élargir le spectre d'activité catalytique est d’une importance capitale pour une chimie respectueuse de notre environnement.Cette thèse se concentre sur la conception de nouveaux complexes de métaux de transition (cuivre et palladium) basés sur deux classes différentes de ligands organiques : les benzotriazolyle-phénolates et les phosphonates. La synthèse et la caractérisation de nouveaux composés a été réalisée par différentes méthodes physico-chimiques (électrochimie, EPR, UV-vis, IR, cristallographie aux rayons X) et la chimie théorique. La génération et la caractérisation des différentes espèces réduites et oxydées nous ont aidés dans la détermination des mécanismes possible. Les composés obtenus ont été utilisés avec succès comme catalyseurs dans divers procédés tels que: la production d'hydrogène, l'oxydation d'alcool et le clivage d'ADN.Nowadays, the ability to synthesize new bioinspired metal catalysts to improve and broaden the spectrum of catalytic activity is of paramount importance for sustainable chemistry respectful for our environment. This thesis is focused on the design of transition metal complexes (copper and palladium) based on two different classes of organic ligands: benzotriazolyl-phenolates and phosphonates.Different original complexes based on palladium and copper were synthetized from benzotriazolyl-phenolate and phosphonates ligands. The characterization of the new compounds was performed by different physical and physico-chemical methods (electrochemistry, EPR, UV-vis, IR, X-ray crystallography) and quantum chemistry. The generation and characterization of different reduced and oxidized species helped us in the possible mechanisms determination. The obtained compounds were successfully employed as catalysts in different processes as: hydrogen production, alcohol oxidation and DNA cleavage

2,6-Bis(bromomethyl)pyridine

In the title molecule, C7H7Br2N, the C—Br vectors of the bromomethyl groups extend to opposite sides of the pyridine ring and are oriented nearly perpendicular to its plane. In the crystal, the molecules related by a c-glide-plane operation are arranged into stacks along the c axis, with centroid–centroid distances between neighboring aromatic rings of 3.778 (2) Å. A short Br...Br contact of 3.6025 (11) Å is observed within a pair of inversion-related molecules
