Synthesis and Characterization of Pyridine Transition Metal Complexes of Ni (II), Cu (I) and Ag (I) - Abstract
The complexes of Ni (II), Ag (I) and Cu (I) have been synthesized using pyridine as ligand. The three complexes have been characterized by melting point determination, solubility test in different solvents, physical state, colour and molar conductance. Pyridine is a mono-dentate ligand. The structure of the complexes has been confirmed by elemental analysis, its study revealed that the metal complexes seem not to undergo any form of decomposition when stored for a long period in the reagent bottles except for Ag (I) complex which is photosensitive while the other complexes Ni (II) and Cu (I) were not air sensitive and were handled with ease. The melting point of the complexes was relatively high ranging from 80 – 172 OC and the reason for its high melting point may be due to the formation of a stable oxidation state as in the case of Ni (II) with a d8 configuration. The Coordination compounds were prepared by the reaction of pyridine ligand with metal salts and the compositions of the complexes by the elemental analysis are recorded together in tables.
