TL;DR: The cis configuration between the hydroxo and the carboxylato and the three amino groups of the tetradentate, tripodal ligand tris(6-neopentylamino-2-pyridylmethyl)amine favors the formation of hydrogen bonds which stabilize the hydoxo-Feiii complex 1.

TL;DR: In this paper, the reaction of Cu(ClO4)2·6H2O with l -glutamic acid ( l -glu) in 1:1 or 1:2 molar ratio at pH 5 gave only the complex [Cu( l −glu)-(H 2O)]·H2

TL;DR: The UV-vis and ESR spectral data indicate that the increase of NH(2) groups of ligands causes the structural change from trigonal-bipyramidal to square-pyramidal geometry, which is regulated by a combination of steric repulsion and hydrogen bond.

TL;DR: Ruthenium(II/III) complexes with tripodal tris(pyridylmethyl)amine ligands bearing one, two, or three pivalamide groups or neopentylamine ones at the 6-position of the pyridine ring have been synthesized and structurally characterized.

TL;DR: A novel copper(II)[bond]OOH complex with functional ligand that can form a hydrogen bond with the distal oxygen of hydroperoxide has been designed and prepared as a structural/functional model of dopamine beta-hydroxylases, whose spectroscopic characterization and decomposition rates have indicated that the Hydroperoxide is activated through the hydrogen-bonding interaction with thedistal oxygen.
