Abstract: This dissertation describes the synthesis, characterization, and biological properties of complexes of nicotinamide/nicotinic acid as primary ligand and nitrite ion/cyanate ion as secondary ligand for the Cr(III), Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Hg(II) metal ions. Chapter 1 of this dissertation discusses introduction and a vast majority of the work that has been previously explored of substituted pyridine metal complexes. Chapter 2 discusses the aim and scope of the work. Chapter 3 is committed to the various analytical techniques and their interpreting methods. Chapter 4 is devoted to the synthesis, characterization, and bio-potential properties of nicotinamide and nitrite ion metal complexes. Chapter 5 considers the synthesis, characterization, and bio-potential properties of nicotinamide and cyanate ion metal complexes. Chapter 6 is devoted to the synthesis, characterization, and bio-potential properties of nicotinic acid and nitrite ion metal complexes. Chapter 7 is devoted to the synthesis, characterization, and bio-potential properties of nicotinic acid and cyanate ion metal complexes. It is revealed from the analytical, conductance, magnetic, infrared, electronic spectral data, EPR, NMR, CV and thermo analytical techniques in which the organic ligand act as a neutral monodentate and coordinating through pyridine nitrogen atom. The geometry of the complexes is assigned as distorted octahedral. The conductance measurements show that all the metal complexes are non-electrolytes in nature. The decrease in pyridine ring imine group stretching frequency in all the complexes confirms the coordination site of the ligand is pyridine ring nitrogen. Electrochemical properties of the metal complexes revealed the quasi-reversible one electron/two electron transfer redox process. Some of the complexes contain crystallisation water and are thermally stable; this is mentioned by IR spectral studies and confirmed with thermo analytical methods.
