Crystal structure of aqua[N-(2-oxidobenzyl-κO)-L-leucinato-κ²N,O](1,10-phenanthroline-κ²N,N′)nickel(II) pentahydrate

Abstract

The NiII atom in the title compound is in a distorted octa­hedral coordination geometry with two N atoms of the phenanthroline ligand, two O and one N atom of the 2-[(2-hy­droxy­benz­yl)amino]-4-methyl­penta­noic acid ligand and one water mol­ecule. In the crystal, the complex mol­ecules and solvate water mol­ecules are associated via O—H⋯O hydrogen bonds into a three-dimensional network.

Structural characterization and DFT study of bis{(S)-2-[(2-hydroxybenzyl)amino]-3-(4-hydroxyphenyl)propanoato-κ2 N,O}(1,10-phenanthroline-κ2 N,N′)cadmium(II) tetrahydrate

“…The formed ligands are more conformationally flexible at the coordination site, thus not necessarily forming planar chelate rings (Koh et al, 1996). In recent years it has also been found that phenanthroline, another ligand used in this study, has ISSN 2056-9890 extensive important roles in a variety of fields (Faizi & Sharkina, 2015;Faizi et al, 2017). In this paper we report the synthesis and structure of a new cadmium complex with an l-tyrosine-derived ligand synthesized by the reduction of a Schiff base precursor.…”

Crystal structure of bis[(S)-2-(2-hydroxybenzylamino)-4-methylpentanoato-κ2 N,O 1](1,10-phenanthroline-κ2 N,N′)cadmium dihydrate

“…In attempts to achieve stable polydentate ligand systems retaining the initial donor sets, it was found that reduction of Schiff bases to amines allows the formation of stable complexes (Koh et al, 1996). Phenanthroline and phenanthroline-derived ligands also have important roles in many fields (Faizi & Sharkina, 2015;Faizi et al, 2017). Herein we report the synthesis and ISSN 2056-9890 structure of a new hydrated cadmium complex, [Cd(C 13 H 18 NO 3 ) 2 (C 12 H 8 N 2 )]Á2H 2 O, with a phenanthroline ligand and two ligands derived from l-leucine.…”

Crystal structure and DFT study of bis{(S)-2-[(2-hydroxybenzyl)amino]-4-methylpentanoato-κ2N,O}(1,10-phenanthroline-κ2N,N′)nickel(II)

“…Any change in its concentration leads to metabolic disorder (Kolodziej, 1994). With the discovery of the biological importance of nickel, it is essential to study its complex formation with amino acids in order to ISSN 2056-9890 gain a better understanding of the functions of their complexes (Faizi & Sharkina, 2015). Therefore, we report here the preparation and the crystal structure of a nickel(II) complex with the formula: [Ni(C 13 H 18…”
