The organic compounds have a wide applications in more than field like ( formation of drugs , preparation of antimicrobial compounds , as a ligands in coordination chemistry, as a reagents , as liquid crystals ,…) for this reason, we reported preparation of novel compounds from (azo or amide )- crystals and their identification via many instrumental systems like ( I.R , H.NMR , Polarized optical measurements, physical characterizations).
