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

Abstract

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)(H2O) 3](ClO4)2·H2O (M = Co II, NiII) 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. © 2013 Taylor & Francis.
