Physicochemical Data

The reaction of Hg2+,Cd2+,Co2+, and Ni2+ ions with 1 mol of the ligands 2-methylquinoline-4-ol,3[(diethylamino)methyl]-2-methylquinoline-4-ol, and methyl-3-(4-hyrdoxy-2-methylquinoline-3-yl)-2-(triphenylphosphoranylidene)propanoate, has been investigated to give the corresponding 1:1 metal:ligand complexes. Reaction of 2 mol of the ligand gave the corresponding 1:2 metal:ligand complexes. The coordination takes place only through the quinoline nitrogen atom. The spectroscopic and the physicochemical data of the new metal complexes are discussed.
