The  new  ligands  have  been prepared in this  work  (potassium 2carbomethoxy amino 5-5trithiocarbonate 1,3,4-thiadiazole ) (LI) was prepared from 2-carbomethoxy amino-5-mercapto 1,3,4-thiadiazole  with  CS2 in alkali media , while the second  ligand    was  prepared  from 2-N(4-N,N-dimethylamino benzyliden)-5-mercapto 1,3,4-thiadiazole  with  CS and in alkali media  to obtain potassium 2-N( 4-N,N-dimethylaminobenzyliden )4-trithiocarbonate 1,3,4thiadiazole ( LII).The  products  were  isolated  and  characterized  by  appropriate physical measurement , vibratio

 Some transition metal chlorides, CrCl3.6H2O, FeClO,CoCl2.6H2O, NiCl2.6H2O and CuCl2.2HO were investigated spectroscopically in the newly prepared choline chloride/ tartaric acid ionic liquid at room temperature.

This work involves synthesis of different five, six and seven member heterocyclic ring utilizing 2-aminopyridine as a starting material.This work is divided into four different parts:
Part One :
This part involved the synthesis of 3-biphenyl-4-ylimidazo[1,2-a] pyridine[1], 3-phenylimidazo[1,2-a]pyridine [2], imidazo[1,2-a]pyridine-3(2H)-one [3], 2H-pyrido[1,2-a]pyridine-2,4-(3H)-dione [4], N,N'-1,4-
