تحضير و دراسة طيفية لمعقد النيكل (11)‎ مع قاعدة شيف جديدة مشتقه من 4-امينو انتي بايرين

الملخص EN

This research included the preparation of new schiff base ligand derived from 4-aminoantipyrine and o-amino phenol as a first step, and then reacted the result compound with salicylaldehyde to give (2-(4-(2-hydroxybenzylideneamino)-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-ylideneamino)phenol(HDPY)) in the second step .

Ni(II) complex was prepared with the new ligand .the ligand and its complex was identified by using Uv-Visible, FT-IR and H-NMR spectroscopies and micro elemental analysis by C.H.N.S analyzer and atomic absorption spectrophotometer also by the magnetic susceptibility and molar conductivity measurements .

these studies showed that the coordination site of Ni (II) with the ligand through the nitrogen atoms of the two azomethene groups.

from these observations we can suggested the square planner geometrical structure for Ni (II) complex.
