Synthesis, structure and thermokinetic studies on perchlorate salts of metal complexes containing a formamidine-type ligand

Two formamidine-type transition metal complexes of N,N′-bis(4-acetyl-5-methylpyrazol-3-yl)formamidine (ampf) have been synthesized by a template reaction in methanolic solution of the corresponding metal perchlorates and 4-acetyl-3-amino-5-methylpyrazole (aamp) precursor in the presence of triethyl...

Description
Summary:Two formamidine-type transition metal complexes of N,N′-bis(4-acetyl-5-methylpyrazol-3-yl)formamidine (ampf) have been synthesized by a template reaction in methanolic solution of the corresponding metal perchlorates and 4-acetyl-3-amino-5-methylpyrazole (aamp) precursor in the presence of triethyl orthoformate. Compounds of composition [M(ampf)(H 2 O) 3 ](ClO 4 ) 2 ·H 2 O (M = Co II , Ni II ) have been formed. The crystal and molecular structures of the compounds have been determined by X-ray crystallography. The complexes were characterized by IR spectroscopy. The thermal stability and the decomposition kinetics of the two potential explosives were determined by thermal methods.
