Notes:
Ferrous, cobalt and nickel benzylidene picramates have been prepared by treating the corresponding aqueous sulphate and chloride solutions with sodium salt of 4′-dimethyIaminobenzylidene-2-hydroxy- 3.5-dinitroaniline. A metal: ligand ratio of 1:2 has been established in all these cases with the help of micro-analysis and confirmed by spectrophotometric, colorimetric and magnetic susceptibility measurements. I.R. studies of metal benzylidene picramates show N + M coordination, where M is iron, cobalt or nickel. Explosive properties of these benzylidene picramates have also been studied and it was found that the thermal stability of these benzylidene picramates increases as the atomic radius of the metal decreases. Ferrous, cobalt and nickel benzylidene picramates increased as the atomic radius of the metal decreases.
