Atomic absorption and molar ratio Spectroscopic evidence showed that the binding of metal ions were through the azide(μ-1,1-N 3 ) Triazonine (3,5 -N 3 ) and carboxyl moieties , resulting in a six -coordinating metal ions (Cr(III),Mn(II),Co(II),Ni(II) and Cu(II) ) .The VO(II) , Zn(II) ,Cd(II), andHg(II) were coordinated through azido (μ-1,1-N 3 ) , triazonine(3,5-N 3 ) only forming square pyramidal for VO(II) and tetrahedral geometry for Zn(II) , Cd(II) ,and Hg(II)β, ́ for Ni(II) , Cr(III) complexes were calculated too . The molar ratio and metal estimation showed , the ratio of L-AZ to metal ions was (10:1) ; (M/L) .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
