| Abstract: | Infrared studies of pyridoxal isonicotinoyl hydrazone and of three similar chelating agents in solid state brings out, after complexation with iron (III), the deprotonation of phenol for all the compounds; for those which possess the pyridoxal group, a deprotonation of hydrazine leads to a transformation of the linkage between the rings and for the others, the drastic shift of the carbonyl band proves its engagement in the association with iron. |
