Crystal structure of N,N,N′,N′-tetramethylethanediamine

The title compound N,N,N′,N′-tetramethylethanediamine, C6H16N2, is a bidentate amine ligand commonly used in organolithium chemistry for deaggregation. Crystals were grown at 243 K from n-pentane solution. The complete molecule is generated by a crystallographic center of symmetry and the conformation of the diamine is antiperiplanar. To investigate the intermolecular interactions, a Hirshfeld surface analysis was performed. It showed that H...H (van der Waals) interactions dominate with a contact percentage of 92.3%.

Selective Oxygenation of C-H and C=C Bonds with H2O2 by High-Spin Cobalt(II)-Carboxylate Complexes

Four cobalt(II)-carboxylate complexes [(6-Me3-TPA)CoII(benzoate)](BPh4) (1), (6-Me3-TPA)CoII(benzilate)](ClO4) (2), [(6-Me3-TPA)CoII(mandelate)](BPh4) (3), and [(6-Me3-TPA)CoII(MPA)](BPh4) (4) (HMPA = 2-methoxy-2-phenylacetic acid) of the 6-Me3-TPA (tris((6-methylpyridin-2-yl)methyl)amine) ligand were isolated to investigate their ability in H2O2-dependent selective...

Atmospheric Carbon Dioxide Capture as Carbonate into a Luminescent Trinuclear Cd(II) Complex with Tris(2-aminoethyl)amine Tripodal Ligand

Spontaneous atmospheric CO2 capture as carbonate anion occurred in the synthesis of a trinuclear Cd(II) complex with tris(2-aminoethyl)amine ligand. In reaction two types of compounds were obtained and structurally characterized by X-ray diffraction on a single crystal: initially [{Cd(tren)}3(tren)](ClO4)6·2H2O (1) and subsequently [{Cd(tren)}3(tren)][{Cd(tren)}3(µ3-ηCO3)](ClO4)10 (2). The carbonate anion replaces partially the bridging tren molecule and coordinates in a µ3 fashion. The luminescent properties of the compounds were investigated.

Amine-ligand modulated ruthenium nanoclusters as a superior bi-functional hydrogen electrocatalyst in alkaline media

Amine-ligand modulated Ru nanoclusters (Ru/PEI-XC) as an active and stable bi-functional catalyst for the alkaline hydrogen oxidation reaction (HOR) and hydrogen evolution reaction (HER) are successfully developed.
