Abstract :
The reaction of pentadentate salicylaldimine ligand 2-((2-(2-(2-hydroxybenzylideneamino)ethylthio)ethylimino)methyl)phenol (H2L) and its related hydrogenated derivative 2-((2-(2-(2-hydroxybenzylamino)ethylthio)ethylamino)methyl)phenol (H4L1) with hydrated nitrate and perchlorate nickel(II) salts afforded polynuclear metal complexes. These complexes were characterized by elemental analysis, IR and UV–Vis spectroscopy, molar conductance and variable temperature magnetic measurements. Single crystal X-ray diffraction of [(NiL)2]·CH3OH·4H2O (1) and [Ni3(H2L1)2(NO3)2] (3) complexes has revealed the presence of an octahedral coordination geometry around the nickel ion. The magnetic data indicate that a moderate antiferromagnetic interaction is present in complexes 1 and 3.
