CHM03 Preparation and Identification of Niacin Metal(II) Complexes

Abstract

Using nicotinamide as a secondary ligand and amino acid anthranilic acid as a primary ligand, the research involves the manufacture and identification of type mixed ligand complexes of M⁺² Ions. The composition of the mixed ligand complexes, Cl [M(NA)₂(A)], where nicotinamide (C₆H₇N₂O) represented (NA) and anthranilic acid (C₇H₇NO₂) represented ethanol was used as a solvent while the ligand and metal chlorides were introduced to a room temperature reaction. The following molar ratio was needed for the reaction: containing M⁺2 ions, where M(II) = Mn(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II), Hg(II), and pd(II). The findings demonstrated that the deprotonated ligand (anthranilc acid) to anthranilate ion (A) by employing (NaOH) coordinated to metal ions as bidentate ligand through the amine's nitrogen atom and the oxygen atom of the carboxylate group (COO^-).
