Synthesis, crystal structures and magnetic properties of two new nickel(II) complexes with α-amino acid Schiff base
TLDR
In this paper, two nickel(II) complexes [Ni(napgly)(MeOH)] n (1) and [Ni[napphe)(H2O)2(MeOH] · H2O (2), where the tridentate Schiff-base ligands H2nap gly and H2 napphe are condensed from 2-hydroxyl-1-naphthaldehyde with glycine and L-phenylalanine, respectively, were prepared and structurally characterized.Abstract:
Two nickel(II) complexes [Ni(napgly)(MeOH)] n (1) and [Ni(napphe)(H2O)2(MeOH)] · H2O (2), where the tridentate Schiff-base ligands H2napgly and H2napphe are condensed from 2-hydroxyl-1-naphthaldehyde with glycine and L-phenylalanine, respectively, were prepared and structurally characterized. In 1, two inversion-related Ni(II) ions were bridged by two O atoms from the phenolate groups of two napgly anions, forming a centrosymmetric dimeric unit which was further linked by carboxylate groups to give a two-dimensional network. Magnetic susceptibility studies performed on the complex revealed anti-ferromagnetic coupling between the metal centers. In 2, the crystal structures of the complex displayed a distorted octahedral coordination geometry in which the ONO-donor Schiff base was bonded to the metal. Intermolecular H-bonds linked the compound into a 2-D layer structure.read more

Rational design of two bpy-bridged 3D and 2D CoII open frameworks with similar amino-acid-based Schiff bases
TL;DR: Two novel bpy-bridged Co(II) Schiff base complexes have been synthesized by the hydro(solvo)thermal reactions of corresponding amino-acid-based Schiff bases, bpy and Co(NO(3)·6H(2)O), and magnetic studies show the dominant antiferromagnetic coupling between the Co( II) centers mediated by the syn-anti-COO(-)-bridges in both complexes.
