Pyridine is structurally similar to benzene,The pyridine ring possesing six π electrons that are
delocalized over the ring. In Pyridine five methine (=CH−) group and one nitrogen atom constitute
six a membered ring . It is a weakly basic colorless liquid with unpleasant fish smell .The pyridine
rings occurs in importance compounds including pharamaceuticals ,and vitamins .Basicity of pyridine
is governed by availability of lone pair of electron and is behave as tertiary amine. A probe into the
literature survey clearly reveals that no work has been carried out for Cu(II) complex of(2,3 –
dichlorobenzylidene picolinohydrazide) 2,3 diclorobenzaldhyde and 2- pyridine carboxylic acid
hydrayide.work deals with highly effective medicinal isoniazide derivatives, have been synthesized
from Schiff base route and also its Cu(II) metal complex were synthesized.The structure of the ligand
dichlorobenzylidene picolinohydrazide and its Cu(II) complex were undergone various spectral studies.
In present work an attempt has been made for the synthesis of (2,3dichlorobenzylidene
nicotinohydrazide) its metal complex of Cu(II) and to establish the structure through the Analytical
Techniques such as Elemental test and TLC and Spectral Studies such as IR ,1H NMR and 13C1
NMR methods used for their characterizations.
