Synthesis and characterization of mercury(ii) complexes containing 2,9-dimethyl-1,10-phenanthroline by sonochemical method

Synthesis and characterization of microstructured crystalline complexes of [hgi2(c14h12n2)] and [hgbr 2(c14h12n2)] were carried out from the reaction between 2,9-dimethyl-1,10-phenanthroline,mercury acetate,ki,and kbr,respectively,in methanol by sonochemical method. the reaction conditions were optimized under ultrasonic irradiations and without it. characterization of the complexes was performed by elemental analysis,xrd,sem,ftir,and thermal analysis (tg/dta). the results showed that sonochemical method caused significant reduction of the reaction time. then the products were put under supercritical condition in a teflon-lined,stainless-steel parr bomb container and heated at 150°c for 48 h. the results showed that the chemical formulas of the complexes were not changed; however,the particle sizes were reduced and porosity increased. © 2013 m. ranjbar et al.
